The Houthi one is a great example. I think caution is needed here as the U.S. is still trying to put together the picture.
What the Mason had to do to ensure they were defeated was fire. Medium-range cease barrel missiles, long-range standard missiles, and a spectacularly expensive Nulka deceptive jammer.... This is high level. It doesn't get any more sophisticated a response than that. As you say, it's against somebody, a rebel force in Yemen, not one of the leading lights of naval capability, that was able to fire this from the back of a truck.
Let's go look at some of our NATO allies, and what they are doing. Britain is probably going to hit the 2% target, but the way she got there is absolutely terrifying. Several years ago, she looked at the threat and said, “We don't need maritime patrol aircraft anymore” and they got rid of their Nimrods. Then the Russians started coming right up to their submarine base in Faslane, and guess what the U.K. is doing today? It's making a rush buy of P-8 Poseidon aircraft, the most expensive in the world today, and I'm sure they are paying panic prices for the lot.
You then see a drop-off in defence spending percentages the further from Russia you are, certainly in naval capabilities, with quite limited capabilities for all except France. Others are staying closer to home. The bottom line is, there's a real need to reassure places like Poland and the Baltics that the U.S. will be there, and that she's going to have some high-capacity help from us.
I'll turn it over to Ken Hansen.
