Secondly, ZERO countries in the world have non-fragile infrastructure. America's infrastructure is better than most countries and definitely above average even among developed countries, except public transportation.
This will never be possible, even if America does nothing 'wrong' against anyone else. As long as America (flaws and all) is a better place to live than other countries, and can be used as an example of how things can be better (though not perfect), and so will be a target of powers that don't want their own people thinking about improving things.

There are also plenty of bullies out there, who are only checked by American power, and wouldn't mind the US being more isolationist.
There are all sorts of problems of how America interacts with the world, but there are many other countries who would do worse things IMHO. America simply existing generates enemies.
We should try to make enemies only when attacked. Not make enemies out of adversaries.
There are innocent people who have done nothing wrong, and yet other folks want them wiped out of existence.
I'm sure we can all think of examples from history where this is true, both the recent and distance past.
This comment is not based in reality. Does Australia have many enemies? Does South Korea? Does Japan? Taiwan?
