We’re tired of being the world’s policeman - as for the West, our message is unequivocal - our allies need to stop being freeloaders and defend themselves. They’re rich enough to afford it.
As for Crimea, we don’t have any vital interests there. This is a majority Russian region and since they freely voted to return to Russia - we have no reason to be involved there, period. Other people’s lives are none of our business just as our lives are none of their business.
It was acceptable to support a war-devastated world in the special case of the Cold War, it’s quite another situation to condemn our nation to slow death by playing world policemen. History teaches that no nation, no matter how powerful, long survives a unilateral attempt to impose a universal peace.
