Some websites power index measurement is not a standing army. I’d agree we have the most powerful military, but it’s not the largest. Our Army in 1865 was larger than our army now.
Topic at hand, fund Ukraine, let them fight our near peer for all the reasons previously stated including doing the right thing. For your point on downsizing, we have to be careful deciding to drastically cut our military and use it to fund friendly militaries because not everyone may stay friendly forever, and we are giving them the say on what the appropriate use of the military is. I’m not against looking at our budget, but we need to know what we are getting ourselves into.
