Simply charging other nations a tariff, something these same nations have been doing to American companies for 80 years is NOT some form of isolationism. Nor standing up to centralized communist nations.
The assertion is absurd and pushed by people who want America to collapse. You have $37T in debt so pick your poison, massive tax increases, the loss of your social nets through deep cuts, and/or invading other nations for their resources. Of course there is the last option, hyper inflation to pay the debt and lose the U.S reserve currency status.
Of these three, I'd say informed Americans would be far more supportive of tariffs.
Ditto for support for Israel, which has been U.S policy for decades. America must call them out if they risk everyones reputation or violate the Geneva Convention but the general consensus is "Israel is a democracy with a stable government, Judeo-Christian (yes, Jesus was probably promoting 80% fidelity to the Torah) and elected governments. They are, for the most part (even as I hear so many former CIA and others call out Israel for abuses) a U.S ally." As with any nation (including Canada or the U.K), America has to hold them to account if they endanger American interests. None of this is new. The U.S has been backing Israel for many decades and they share intelligence.
America can and should rule the world as long as it is a benevolent global leader for peace, operating in a manner to ensure peace among nations and prevent bullying and/or WWIII from breaking out.
I want peace everywhere. I wish there wasn't any evil in the world. Peace through strength is a real concept as Reagan drove home. America doesn't need to get entangled in every war but it must remain the paramount nation to prevent it.
I'd also argue it should promote its Constitution and defend it domestically and around the world. If every other nation operated under a similar U.S Constitution, the U.S (and some other Western nations) would be 3x the economy it is today,
