"...they will probably invite UN soldiers in to help..." This is a weird misconception some people have. UN soldiers won't be called to fight in a war. UN doesn't have soldiers. Member countries have soldiers and the UN can ASK soldiers from member countries. I've served on a few trips like that since the early '90s. Those member countries decide on their own if they want to send soldiers to a particular problem area or not. I know several countries, including mine, where the constitution forbids active participation in the skirmishes between the belligerents. We could participate only, if attacked ourselves or if civilians were attacked. My parliament would never allow us to be sent to US if there was an active civil war going on there. Certain specific US troops train with my guys in my country every year and many of us have served together in places like Libanon, the Balkans, and Afganistan. It would even be stupid to send us because many of us would support the US military in this particular case.

A fun little thought for you - let's say a lot of us (troops in countries who have served with US troops before), would tell the UN: "No, we won't send troops to US". Simply, because many of us would NOT apply for that particular mission. So who would send troops? China? Russia? Some African countries? With all due respect, troops from African countries are not well equipped, and if China or Russia did send troops, do you REALLY think we would fight alongside our "enemies" against dudes we've served together with? We would come in flocks as voluntary and fight on the US MIL side. Because I may not share your beliefs, but I share the idea of free speech and I will fight for your right to disagree with me.
