In two and a half years, Donald Trump and his national security team have managed to worsen virtually every aspect of American national security policy. Trump has bullied and harangued our traditional West European allies and, as a result, bilateral relations with Britain, France, and Germany have become more difficult. France, Germany, and even Japan have begun to rethink their security policies because of the uncertainty that surrounds dealing with the Trump administration. President Barack Obama left Trump a path for dealing with traditional foes in Cuba and Iran, but the president has made these issues far more problematic and, in the case of Tehran, raised the specter of confrontation.
