President Trump says he's considering options to intervene in Iran, amid ongoing protests. The threat comes hot on the heels of a dramatic US intervention in Venezuela, and threats to take over Greenland. Together, they suggest a shift in US foreign policy towards more open interventionism. Jonathan Freedland takes the Long View of US intervention abroad, exploring revealing parallels between current foreign policy and a covert American intervention in Guatemala in 1954.
