The larger point though is that if America keeps flip-flopping on foreign policy as the Presidency rotates between Ds and Rs it's difficult for America's allies to trust you to stick to a plan. I get that the pendulum swings when the Presidency changes but the swings seem larger to the allies now than under previous administration changes. You're in the Iran deal, then you're not. You're for climate change initiatives, then you're not. You're in WHO, then you're not, then you are again. You're in NATO, then you're questioning if NATO is relevant. America's allies want America to lead, they need America to lead, but they also want to know that there will be some consistency in direction. If the US is unable to steer the good ship Freedom in a consistent direction, it is prudent of the allies to consider other ships. There are no better options, but you can't blame the allies for considering alternatives.
