If Russia wants to invade, lets watch her, but keep out of it. Revolting in Ukraine has been brewing since the USSR broke apart. The reason, when USSR broke up everyone took their Communist hat off, reached on the right side of the desk and put on a Capitalist hat. As soon as they did this, they went back to work doing what they always did. No change. Why? Because they didn't know what else to do. It has taken two generations to get them here and they still don't have a clue how free enterprise works. People in power or office resist change terribly bad.
Please U.S. keep out of it, we will just loose another potential friend, and could start a war we don't want.
