Putin's Choice - It's a War of Choice

I thought it was a brilliant line from the president saying, this is a war of choice. It's Vladimir Putin's choice and he could end this war with one word: "We will not tire" The real question is over the next couple of years, do we demonstrate to the Russians that we actually have the staying power? I don't see anything in the last couple of days to suggest that this war is poised to end.
