 Well, thanks. It's a great question, Steve. It's something I've written about and very fair. What I would say, and this gets back to some of the sort of key theoretical points that I proceed from and I go into in my book if people are interested, which is that, and I think this has only become more clear over the course of the war in Ukraine, a very tragic war, is that what really matters in terms of the ability to coerce other countries to do something they really don't want is direct military power.
