Very quickly, I would say Secretary of State Kerry had it right on March 2 when he appeared on a number of talk shows here and said that all options are on the table.
None of us wants the military option. I'm not advocating it, and I realize there's a need not to raise false expectations among Ukrainians that the United States or Canada or Europe is going to come running to their rescue militarily. But I also think we should not be telegraphing our limitations to Putin. We shouldn't be drawing the line saying that we'll do up to this point. Otherwise, frankly, I don't see a reason to send ships to the Black Sea if we're already telling Putin we're not going to use them. It seems to me we want to keep Putin guessing as to what we might do, not to escalate the situation, but just the opposite, to try to de-escalate it so he thinks there could be other ways we would respond.
