In effect, Trump has walked away.
Cut off funding of weaponry, after Monday NIXED further sanctions, and to nobody's surprise other than the Euroweenies NIXED US ground troops as peacekeepers.

He gave the agreement his best shot, but what happens, happens.
We are returning to our more traditional role of Europe’s backstop, rather than being the lead dog.
