Oh and as a sweet bonus to economic war, you can war on an ally that pisses you off without raising a stink. Euroweenies are in the cross-hairs and that 7.5 billion WTO ruling is going to be fun. The Weenies have to sit there and take it and can’t retaliate. Carefully crafted tariffs are going to royally piss off the “right” people who wield the most political clout in Germany, France, Spain etc. and Poland being exempt as a real ally is going to make blood boil.
You’re also assuming that smashing the Kurds would be something that Trump, in his great and unmatched wisdom, considered off limits. I haven’t seen anything in his comments or tweets that indicate that. He knows what Erdogan is going in there for.
