Jeffrey Sachs: 911, Iran & Ukraine

This week on Switzerland, Tom Switzer is joined by Professor Jeffrey Sachs from Columbia University. Subjects include the 25th anniversary of the September 11 attacks: what did America learn –- and what did it fail to learn? How much of the foreign-policy thinking that emerged from that moment still shapes the Trump administration? When will US leaders recognise limits to military and economic power in a messy world that won’t conform to America’s expectations? When will Washington, to use a neoconservative phrase, get mugged by reality?   Plus, is the tide turning against Tehran? After all, Iran has failed to shut Hormuz completely. The global economy has proved remarkably resilient. And the American naval blockade is severely restricting Iran’s oil exports, placing mounting pressure on its already fragile economy. And is Ukraine really winning the war against Russia, as several western commentators allege? Or are Moscow’s strategic gains in eastern Ukraine irreversible?
