This is naive. No other country would dare do this to the US because the US would simply rain literal hellfire upon them.
Your mistake is in equating the US to other countries. You cannot. It is a superpower.
When other countries act hostile to the US, it can simply ignore their sovereignty at a whim, and this is a huge benefit to living in US.
Is it unfair? Sure. Who cares?
People who don't live in a superpower. People who care about international law. People who would rather the most powerful countries didn't act like bullies whenever it suits their interests.
> Is it unfair? Sure. Who cares?
What do you mean, "who cares"? Obviously a lot of us not from the US care, and many Americans care, too.
This is wrong and hilariously short sighted. Other countries don't respect America due to military might - they do so because of decades of mutually beneficial trade agreements. Soft power is infinitely more useful than hard power.
