So how would you feel if you got labeled as warmongers for that help?
You're welcome to call us warmongers. Just don't expect us to help you fight wars if you do.
Libya was Europe's idea -- we helped when you called -- yet the US still gets blamed for it. If the US had surged more weapons to Ukraine (as some Europeans were requesting), thus provoking Russia to launch a nuke, we surely would've been blamed for that too.
The pattern I've noticed is that anywhere the US has foreign policy involvement (including Europe), there are locals in that region who are both for and against said involvement. People who aren't knowledgeable about the region will generally not know many details, and simply say "oh, the US is involved in a war again". If that's how we're going to be judged, then yes, I want to be involved in fewer wars. And withdrawing from NATO will help with that objective. So I favor NATO withdrawal.
