The Widening War: U.S.-Iran Conflict Strains Global Order From Hormuz to Taipei
The United States has now conducted at least eleven consecutive nights of airstrikes against Iran. What began on July 8 as a stated response to Iranian threats against commercial shipping through the Strait of Hormuz has expanded in scope and intensity. The July 18 strikes were explicitly described by the Pentagon as punishment for an Iranian Revolutionary Guard attack in Jordan that killed two U.S. service members and left one missing. According to Iranian officials, more than 100 U.S. air attacks have now struck targets across Iran, killing at least 50 people and wounding over 500. The European Aviation Safety Agency issued a safety notice on July 22 warning that the security situation in Jordanian airspace has “deteriorated rapidly” since mid-July.
This is not a contained skirmish. Three theaters — the Persian Gulf, the Pacific, and Eastern Europe — are simultaneously under stress. The United States is fighting a shooting war in the Middle East, managing a volatile diplomatic relationship with China, and providing indirect support to a NATO bloc that has pledged €140 billion in new military aid to Ukraine. Whether Washington can sustain credible deterrence across all three is the defining question of this moment.
What We Know
Iran conflict. The U.S.-Iran military exchange began July 8. By July 17, CNN confirmed the U.S. had completed seven consecutive nights of strikes. On July 18, AP News reported the Pentagon launched fresh attacks to “further degrade Iran’s ability to threaten commercial shipping.” France24’s live coverage on July 22 confirms a now-eleventh night of strikes as diplomatic channels have stalled. Iran has responded with widening attacks on U.S. allies across the region.
Houthi naval blockade. On July 20, Yemen’s Houthi movement declared a naval blockade of Saudi Arabia, according to Reuters and Al Jazeera. Saudi Arabia condemned the blockade, which threatens to disrupt oil shipments from the world’s largest crude exporter. Al Jazeera reported on July 21 that Houthis also struck Abha Airport in Saudi Arabia, claiming it as retaliation. The blockade follows months of Houthi attacks on Red Sea shipping under the stated rationale of solidarity with Iran.
U.S.-China tensions. On or around July 17, President Trump delivered a primetime address reviving allegations of Chinese interference in the 2020 U.S. election, according to IBTimes UK and FactCheck.org. Chinese officials, per The New York Times, appear to view the speech as driven by domestic politics rather than foreign policy intent — a reading reinforced by Trump’s apparent simultaneous desire to preserve the trade relationship struck at a May summit in Beijing. USA Today reported on July 21 that Trump subsequently “downplayed” China’s election meddling, saying “we do things to them, too.” The mixed signals are generating strategic confusion among U.S. partners and Beijing alike.
Pacific military posture. The U.S. deployed six 154-foot Coast Guard fast-response cutters to Singapore and the Philippines on July 15, repositioned from Middle East operations, according to NewsNation. USNI News reported on July 17 that Royal Australian Navy and U.S. forces are operating together in the South China Sea under the Pacific Partnership 2026 mission. The Institute for the Study of War documented on July 17 an alleged assault on a Taiwanese think tank CEO in Taichung by a Hong Kong national, which Taiwanese authorities characterized as likely transnational repression. Asia Times reported that China conducted a submarine-launched ballistic missile (SLBM) test in the Pacific — its first publicly acknowledged one in decades — prompting CSIS to call for a ballistic missile launch notification agreement between Washington and Beijing.
China-Russia naval exercises. China and Russia wrapped up Joint Sea 2026 naval exercises near Qingdao before launching joint Pacific patrols, according to Zona Militar and China’s Ministry of National Defense. The exercises, timed alongside the U.S.-Iran conflict, signal continued Sino-Russian military coordination.
Russia and Ukraine. CSIS analysts Benjamin Jensen and Yasir Atalan assessed on July 15 that Russia’s defense industrial base has “significantly reshaped” over four years of war and now constitutes an asymmetric threat: Moscow can rapidly scale battlefield-proven weapons production using a hybrid Soviet-market model. NATO committed $40 billion under its new Drone Edge Initiative, and Germany separately funded 50,000 AI-guided FPV drones for Ukraine. European NATO allies and Canada pledged €140 billion in military aid through 2027, though Neue Zürcher Zeitung reported doubts about whether the full amount will materialize.
Russia-North Korea coordination. On July 21, UPI and NK News reported that Russia and North Korea’s top diplomats issued a joint statement blaming the United States and its allies for “destabilizing” the Korean Peninsula. The statement was coordinated through Moscow’s Foreign Ministry and came days after the two countries accused U.S. allies of “regional provocation.”
Russia sanctions pressure. A bipartisan Senate bill, backed by at least 60 senators and championed by Sen. Richard Blumenthal, proposes 100% tariffs on imports from India, China, Slovakia, Hungary, and Azerbaijan for purchasing Russian oil, alongside broad sector-wide sanctions on Moscow’s economy. India has publicly stated it remains “unfazed.”
What’s Driving It
The U.S.-Iran conflict has at least three separate fuel sources. First, Iranian-backed forces — including the Houthis — have maintained persistent pressure on commercial shipping and U.S. allies throughout 2025 and into 2026, making eventual confrontation structurally probable. Second, the Trump administration appears to be using military action against Iran as a mechanism for regional leverage, particularly in any future negotiation with Gulf states or Israel. Third, the killing of U.S. service members in Jordan created a domestic and institutional pressure that made a substantial response politically unavoidable.
The China dynamic is driven by commercial logic colliding with security logic. The May 2026 Trump-Xi summit in Beijing reflected genuine interest on both sides in restarting trade flows. The primetime speech reviving 2020 election interference allegations — followed almost immediately by Trump’s public minimization of Chinese meddling — suggests the administration is playing two audiences at once: a hawkish domestic base and a Beijing leadership focused on economic stability. Foreign Policy’s July 17 analysis describes U.S.-China relations as “more volatile than ever,” an assessment consistent with the pattern of improvised escalation and improvised de-escalation.
China’s SLBM test and the Joint Sea exercises with Russia carry a different logic: long-term strategic signaling to Washington that military options against Taiwan or in the South China Sea carry higher nuclear risk than commonly modeled. CSIS noted the SLBM test is designed to demonstrate that Chinese nuclear submarines can penetrate the first island chain — a message aimed at Japan, the Philippines, and Taiwan as much as at the Pentagon.
The Russia-Ukraine stalemate, now entering its fifth year, is increasingly being managed by Europe independently of U.S. direction. NATO’s Drone Edge Initiative and Germany’s unilateral drone commitment reflect European recognition that American attention is elsewhere. Russia’s industrial war-economy adaptation, per CSIS, is a structural advantage that attrition-based strategies alone will not overcome.
The Houthi naval blockade of Saudi Arabia introduces an energy variable into an already crowded threat environment. If the blockade disrupts Saudi crude flows meaningfully, oil prices will spike — affecting every government managing post-inflation fiscal pressure.
Implications
For U.S. national security: The simultaneous operational demands of a shooting war against Iran, a gray-zone contest in the Pacific, and indirect support for Ukraine are testing the limits of U.S. force posture. The redeployment of Coast Guard cutters from the Middle East to the Pacific is a visible symptom of resource allocation friction. A prolonged conflict with Iran strains naval assets needed in the Indo-Pacific. CSIS’s Russia industrial assessment is a warning that the longer the Ukraine war continues, the more difficult it becomes to sustain a deterrence edge against a simultaneously resurgent and adaptive adversary.
For businesses: The Houthi blockade of Saudi Arabia, combined with active U.S.-Iran hostilities, has pushed risk premiums on Gulf shipping and energy logistics to levels not seen since the 2019 Abqaiq strikes. Companies with supply chains dependent on Gulf oil or Red Sea transit face compounding uncertainty. The proposed Senate tariff legislation — if it advances — would introduce 100% tariffs on imports from India and China, two of the largest U.S. trading partners, creating a new compliance and cost planning problem for multinationals.
For allies: European NATO members are operating with reduced U.S. bandwidth. The €140 billion pledge to Ukraine is a statement of intent, but NZZ’s skepticism about follow-through reflects genuine doubts about whether European governments can sustain domestic political support for that level of commitment through 2027. Japan, the Philippines, and Taiwan are watching China’s SLBM test and the Pacific patrols carefully. For Manila, which has seen persistent Chinese coast guard confrontations in the South China Sea, the question is whether Washington’s attention deficit in the Middle East creates operational space for Beijing to press harder in disputed waters.
What to Watch
Iran diplomacy timeline. The France24 headline on July 22 — “diplomacy falters” — is the key variable. Whether any third-party interlocutor (Qatar, Oman, or a European state) can establish a ceasefire framework in the next 10 days will determine whether this escalates into infrastructure targeting inside Iran or draws in additional regional actors.
Houthi blockade enforcement. Declared blockades are only as effective as enforcement. Watch for whether Houthi naval assets attempt to interdict Saudi tankers and how the Saudi Navy and U.S. Fifth Fleet respond. A successful interdiction of even one Saudi tanker would drive a major oil market reaction.
U.S.-China trade framework. Trump’s contradictory signals on Chinese election interference suggest the administration has not resolved its internal debate on China policy. The next 30 days — particularly any joint statement or back-channel communication following the primetime speech — will clarify whether the May summit framework holds or whether the administration is shifting toward confrontation.
Senate tariff bill progression. Sixty Senate co-sponsors is a notable threshold. Whether the bill reaches a floor vote before the August recess will signal whether secondary sanctions on Russian oil buyers is becoming actual policy rather than messaging.
China’s Pacific submarine posture. Following the SLBM test, watch for PLAN submarine activity near the first island chain and any U.S. or Japanese ASW response. CSIS has called for a launch notification agreement; Beijing’s response to that proposal — if any — would be a meaningful diplomatic signal.
Korean Peninsula. The Russia-North Korea joint statement on July 21 is diplomatic positioning, not an operational alert. But continued North Korean weapons production for Russian use in Ukraine, combined with joint diplomatic cover, is creating a security environment on the Peninsula that South Korea and Japan are watching with increasing concern.
