US President Donald Trump hosts Germany’s Friedrich Merz on Tuesday for his first visit with a foreign leader since joining Israel in strikes on Iran that have dragged the Mideast into war.The long-scheduled White House meeting was supposed to focus on the war in Ukraine and rocky EU-US trade relations, part of a wider effort to salvage frayed transatlantic ties.But Trump’s signal that airstrikes against Iran could go on for weeks has upended the global agenda, with Tehran striking back against US bases and allies in the region.For all the latest headlines follow our Google News channel online or via the app.Merz, a harsh critic of the Islamic republic’s leadership, said Berlin shared the Iranian people’s “relief” that the “mullah regime is coming to an end.”Yet he declined to “lecture” the United States and Israel on the legality of the Iran strikes aimed at ending Tehran’s nuclear and missile programs.Germany, France and Britain have also said they will only assist their allies in
