U.S.-Iran Tensions Rise Amid German Criticism and New Proxy Spillovers

Energy markets and diplomatic relations faced significant strain over the last 24 hours as the U.S. continues its blockade strategy against Iran. President Donald Trump met with oil executives on April 29 to discuss the global impacts of the months-long maritime pressure campaign, which he described as more effective than kinetic bombing. The meeting coincided with oil prices surging to their highest levels since 2022. Domestically, Iranian Parliament Speaker Mohammad Bagher Ghalibaf condemned the blockade, characterizing it as a U.S. effort to cause internal collapse. Diplomatic friction intensified between the U.S. and its European allies. German Chancellor Friedrich Merz publicly rebuked the current U.S. strategy, stating that Europe is 'suffering' from the closure of the Strait of Hormuz. President Trump dismissed the remarks, claiming Merz does not understand the severity of the nuclear threat. Meanwhile, Russian President Vladimir Putin reportedly used a phone call with Trump to caution against renewed U.S.-Israeli strikes on Iranian targets. On the regional front, back-channel diplomacy appears stalled as Vice President JD Vance aborted scheduled trips to Pakistan for negotiations. Tensions were further exacerbated by reports from Lebanon, where Israeli strikes on April 29 and 30 resulted in casualties among Lebanese army troops. These incidents represent the first direct hits on Lebanese national forces since the current ceasefire began, raising concerns about the potential for further spillover in the proxy conflict involving Iran-backed Hezbollah forces.
