We're all old enough and experienced enough to know how this is going to play out. It's a pendulum. It always has been.
More and more people will have the same attitude as
@Forg and change their travel plans. The tourism, aviation and hospitality industries in the USA will be hit really hard. People will lose their jobs.
In response, the Trump administration will be lobbied to ease back. Because the USA is more-or-less a democracy, and those in charge need votes, that easing will happen and things will return to "normal" until the next immigration scandal or (God forbid) act of terror which causes the government to tighten things again.
Over the past week or so we've seen two major -- really major -- Administration backdowns over tariffs. Once Americans start to suffer, there will be a backdown.
Democracy in action.
