To be honest I don't think he will for a simple reason.
Trump wants power, getting in a war with a powerful opponent won't make him powerful. Ruining relationships, buddying up to Putin and telling people he will beat them up will give him power.
He's a bully.
I completely disagree
Trump only won a small portion of the American voting population our problem is people don't vote, not that most of them support this.
I think if it ever actually came to those lengths Congress wouldn't support it. Congress decides if we go to war, not Trump.
So Russia can steal it again and get what they want it's worked so far
