You seem to be saying “what the hell” we have everything and lets just blow a few billion on Ukraine.
The US spends almost inconceivable amounts on itself. I suggest some research into goverment finances across the board.
You do already have everything you could possibly need for any rational purpose. If money can fix a problem, you have it.
Needless to say, this titanic largess is badly managed, absurdly so. And the associated corruption, in domestic spending and regulation, is where the big corruption money is. But I don’t see anyone being strung up on lamp posts.
It sounds very strange, hearing such complaints about a minor spending category, if you understand the big picture.
