I'm not running for VPOTUS or POTUS. But even _I_ know that you don't lay your cards on the table in anticipation of negotiating with the Russians.
Remember the US has some bargaining cards. We can pull the unproven (read non-functional) missile defense from Poland and the Czek republics in return for Russia ascedeing to Georgia getting into NATO. We also can finally follow through on our promise to get Russia into the GATT. We threaten to kick russian trawlers off the Bering sea and to move the Med fleet to patrolling the Arctic Sea just off the Russian Coast.
That's how you play hardball. And the EU says "no Gas? No parts for your VWs, BMW,s and Mercedes".
yeah it can get ugly. But hardball is possible. Remember, that although Russia can turn off the gas, they also need the Euros. Without the Euros from selling LNG, the russian economy falters. Even more so when the EU stops shipping Russia any goods and locks out their shipping via the Baltic and Black seas. Suddenly the $E that Putin was bribing the population with to look the other way as he consolidates power, stops flowing.
Its economic brinksmanship but again, you can play that sort of hardball. UNLESS, like a numbnut, you lay out all your cards on the table trying to prove that you aren't a numbnut when it comes to foreign policy.
