The guy is a former SEAL, but evidently his background didn't include the course in basic "being slightly aware" of consequences of what he proposes. Especially being the Secretary of Interior in Trump Administration.
Interior Secretary Ryan Zinke says the U.S. Navy can blockade Russia if needed to keep it from controlling energy supplies in the Middle East as it does in Europe.
As I stated not for once, the intellectual level of US political class was in tail-spin for a while and here is another living proof of that. Actually, already today Russia effectively is not dependent on Europe for its energy sales because China and East Asia in general are thirsty for Russian LNG and pipe gas. But if Mr. Secretary wants to try to "blockade" Russian ports (accidentally, I am not sure he understands that this constitutes the act of war), sure--let him try.
Russia is a one trick pony," Zinke said, explaining that its economy hinges on its ability to sell energy. "I believe the reason they are in the Middle East is they want to broker energy just like they do in eastern Europe, the southern belly of Europe."
And here is the problem with most in US power-class, they believe in this with all their hearts. Russia, actually, is a two trick pony--she produces state-of-the-art weapon systems which define current geopolitical balance. But I am sure somebody already briefed Mr. former SEAL on that issue. This, plus the fact, that Russia actually does kill terrorists US supports and, unlike the US, suffered from terrorism on the order of magnitude more than US.
