We can remove them and do the isolationist thing as many have been clamoring for. Then we have no need for bases in Europe or the Middle East. Gulf States can figure out how to live with a nuclear armed Iran or one that has a repository of thousands of missiles to blow up gulf state infrastructure when they misbehave. We can remove the bases in Europe too, and when Russia invades Lithuania the Spanish and Germans can take care of it.

Or perhaps these bases aren’t just in allied countries “at their grace”. These alliance systems don’t just solely benefit America.
