I'll talk to the Romanian piece right now specifically. Having spent almost four months operating with them and having the opportunity to do everything from basic fighter manoeuvres through different scenarios, we certainly found a very willing NATO partner in this.
There are varying capabilities in aircraft. There is always a certain amount of asymmetry as it relates to aircraft capability, but certainly Romania was proving itself to be a very capable partner, and I think we both benefited from that experience.
On the Baltic air policing mission, working with the Portuguese, which we have done for a number of years as part of NATO, it's quite a bit more seamless with the traditional NATO allies like them.
