That's a best case scenario way to look at this. I agree with you on how this looks to his base, and what it gives other Republicans. We all know his base will support him on anything so that isn't saying much. And the Republican party is going to ride this train to get as much as they can until it crashes.
I'm not so sure how it helps him with Europe and China. What are your thoughts there?
IMO his foreign relations have been a disaster. I think the only country he has good relations with is Russia. Everyone else is laughing at him.
This also continues the polarization of the nation, which, I guess can be good for him but that's still TBD. And only someone with a gold fish's memory would let this distract them from the Russian thing.
I tend to cringe whenever intelligence is assigned to the man, but I know that's wrong and I should be more open minded.
