Well, of course the initial attempt was to deter the invasion itself a year ago. There sanctions failed. And since then, as you say, we've been trying to disrupt and degrade the Russian military. Obviously the Russians are responding. They are shape shifting. They are switching to war economy. And so while we clearly are tightening the net, we're going after entities in third countries now, which is good to see, I think the sanctions will take a while to have the effect that we all wish they would, which is to disrupt and degrade the Russian military."
