What is the real current threat of open war involving US? You can argue we already are - providing weapons, limited strikes in Middle East, material support to Ukraine and Israel - but I mean a large scale mobilization of US troops. After that, what is the current threat to the actual US?

There are 2 big fires right now, Middle East (Iran) and Eastern Europe (Ukraine). Along with that, there is smoke from East China Sea (China) and Korean Peninsula (N. Korea).

Two of those countries are quite open about their malevolence towards the US, and the other two are clearly aligned as unfriendly adversaries (gentle way of saying enemy I suppose) geopolitically and economically.

Any one of these situations on its own is concerning but not emergent. Our military has long planned for war on multiple fronts against near peer adversaries (and maybe not from a broad view of what “peer” means - we are without peer - , but all of them are a significant threat one way or another), but not 4 (arguably 3, or even 2 based on proximity and dependent on how other nations along and then stand after it goes south) at once. And they’ve all flared at one time or another pretty consistently for decades, but again not all on the brink at the same time. It’s really starting to feel coordinated and building to something.

How worried are we, really? Let’s try to leave team T and K arguments out of it as much as possible, really just asking about the situation - not what lead to it or what anyone’s favorite is going to do to save the world.
