A lecture (video) by and with Anatol Lieven, of King's College London held on May 14. As usual Lieven, who knows East Europe well, gives a sane realist perspective and accordingly damns the foolish "western" policies with regard to Ukraine and Russia. With about 100 minutes the talk and Q&A is quite long but worth your time.
Aside from Ukraine there is an important point Liven makes during the Q&A not with regard to Russia but to China. At 1:25h Lieven talks about false "security guarantees" given by the U.S. and UK, how no one is willing -in the end- to stick to such. This well known fact in general weakens such "guarantees".
With that in mind he expands to China (1:27:40):
I think the Americans have been profoundly foolish in that regard. It does weaken their credibility in alliances elsewhere. […] If the United States extends to China the kind of attitudes and the kind of policies that it has to Russia over the past generation, then, ladies and gentlemen, we will find ourselves in another major international war which will bring the world economy down in ruins and with it, probably, many democracies around the world including our own. I hope that the fact that an American policy which did this would deserve the results it got will be a comfort to our descendants.
Such fear is not without reasoning. U.S. "security guarantees" already inflame the situation as the new Cold War Heats Up in Asia in the same moment that a devastating financial and cyber war with Russia is shaping up. Foolish U.S. policies on Ukraine have pushed Russia and China (and Iran) into an (informal) strategic alliance which is giving U.S. strategic planers more than a light headache. Can a seapower prevail against a strong, self sufficient landpower alliance?
As the Carnegie Moscow Center remarks:
Whether in the Euro-Atlantic or the Asia-Pacific, great-power relations are becoming more contentious, with a loose Eurasian coalition emerging to reduce the U.S. domination of global politics. This is nothing like the Sino-Soviet alliance of the 1950s, but the consolidation of Russia's pivot to Asia is an important result of the first phase of the Ukraine crisis, which will continue to reshape the global strategic landscape.
The U.S. has no other than Victoria Nuland, and Hillary Clinton who installed her as Deputy Secretary of State for Europe, to thank for this foolish mess.
