Great interview and I think Carter speaks a lot of sense into the saber rattling that is ongoing right now from both sides. Russia have an economic problem that Putin may only solve by not overspending on defence and paranoia but rather on rebuilding his ailing infrastructure and getting back onto the world stage where he belongs. We want Russia involved in the world- we NEED Russia involved - but not as a bear with a headache. That's not going to work.
You forget one thing: this isn't a game. There would be no winner. If you think you and your 'allies' would win then you are a fool- blinded by your own nationalism. WW3 would be global and nuclear. Turkey wouldn't stand a chance.
