Over the past few years we have seen Russia do a number of things contrary to our interests. Selling Kornet missiles to Iraq prior to the 2003 invasion in violation of UN sanctions, helping Iran's nuclear program, invasion of Georgia, invasion of the Crimea, Syria, etc. The concept of selling LNG to Europe is the first move by the US in all that time which may have an effect on Russia's activities. They are very reliant on petroleum-dollars.
I was pretty angry about that at the time.
Russia doesn’t have to be our enemy, but it is for sure they aren’t our friend.
I used to lean pretty pro-Russia but I am becoming a new cold war warrior recently.
