You are debating one hyperbole with another hyperbole.

After all not everyone has Trump as President who thinks the only way to work with allies is to bully them. Will this particular thing going to define US for next 50 years? Probably not. Will countries say fuck it and stop working with US? Definitely not.

But will they ever have same amount of fear or trust or reverence for the US? Absolutely no.

That is now lost. While Iraq and Afghan war wasn't exactly a win for the US, the Iranians have shown that Americans can be had if cards(hands) are right. They now know Americans are completely blind to a president who would sell his mother for the right price and still defend him because they feel invincible and instead of offering a seemingly innocuous job to President's son like Burisma they can now blatantly bribe a jet, pay for access openly and no one in America will care because they believe they are infallible.
