With all due respect what did Russia do that warranted American tax dollars to be sent there instead of say maybe helping the situation at home? Ukraine isn’t even a nato country yet we coddle them and watch at generations die off.
Hate to tell you but every time the USA goes isolationist we get pulled into a war. It’s cheaper to put down certain aggressions when the cost of doing so is small.
Also, just because we might end foreign aid is no guarantee that anything will be fixed at home.
