I’m sick of Europe to be perfectly honest. I wouldn’t mind a complete blockade of imports followed by a tweet: I hope your new trading partner, China, is also willing to protect you against Russian aggression.
Russia and China are currently partners in many things. And Merkel has shown herself willing to go into Molotov-Ribbentrop territory, particularly with respect to the Nord Stream pipeline. It wouldn’t serve us well to hang Eastern Europe out to dry, which is something that Obama was effectively doing. (Remember, the EU is not all of Europe, although they dishonestly refer to themselves as “Europe”.)
