If I may, I'd pile on one more. We all have these experiences we've taken part in. Much along the lines of Ms. Alleslev's question, interoperability is absolutely key. I had the opportunity to be the commander of the air task force during the Libyan war. We arrived, and our fighters arrived, and 48 hours later they were operating over Libya. That was in 2011.
Examples like that are very tangible examples of how important interoperability is within the NATO context.
