German Defense Minister Boris Pistorius publicly blamed Trump for Iran's closure of the Strait of Hormuz on June 21, 2026. Iran reopened its blockade of the critical shipping lane to protest Israeli airstrikes in Lebanon, occurring amid active US-Iran peace negotiations in Switzerland where Vice President Vance is leading US talks with Tehran. The closure matters because roughly 21% of global oil passes through the strait—the blockade is driving negotiations toward a 60-day framework agreement, but Lebanon fighting and Trump's public threats are destabilizing the talks.
