That's an excellent question, sir. I think that if we look at Europe since the end of the Cold War, a certain stability had arisen whereby there was excellent cooperation amongst all parties, both within NATO and the former Eastern Bloc.
I think anytime you have an aggression that we've seen in Crimea and in eastern Ukraine, it has a very destabilizing effect. Certainly for our good NATO allies that are in the Baltics and on, essentially, the eastern flank of NATO, those concerns are seen in a historical context that certainly provides them pause to consider next steps. So, I would certainly say that we've seen a fundamental shift in the geostrategic security construct that Europe has enjoyed for some time.
