And while the Navy is brought up, lets not forget the Coast Guard.
While the Coast Guard is joked about as dollar store Navy, it's a legit military service that has been actively at war against drug smugglers past few years, but gets sent over in previous wars to fight in riverways. This gives the US navy the entire pacific to fight against Russia, and when they do get to the US, there's a second home based one under a completely different administration to fight at the shores.
Hell, I think my biggest problem is I can't think of anything dumb enough before they've already got it
I used to think I was a pessimist. But now after multiple "There's no way people are that dumb" and being wrong I must be an absolute optimist.
