Oh, yeah, I 100% agree. That was the time to step in if anyone actually gave a shit about nuclear non-proliferation.
I consider the complete lack of meaningful response to the 2014 invasion to be both Obama and Merkel’s single most egregious foreign policy failure. Merkel also rapidly thawed relations with Russia after that, and continued to aggressively push for closer ties with Russia, and this is the result. She continues to insist that her approach at the time was correct; she’s going to be remembered alongside the likes of Neville Chamberlain because of it.
