Are you worried about American isolationism?

With Trump's trade wars against America's biggest trade partners, it is certain to push those countries away from the US. If more tariffs are imposed on other parts of the world alongside the notion that America will no longer be 'the police of the world', I see the US shrink its global influence and leave it as a fourth world country with no Allies or massive trade partners if it continues down this route. But how do you feel about these developments? Is isolationism the way to reach the 'American Golden Age' or is this no longer an option with current globalization? Will the future be 'America Alone'?
