Maybe I can answer that question, Mr. Chair.
The U.S. has a presence. They have a training mission also in Ukraine and they follow similar approaches to those we're taking. They're going to continue to train with the Ukrainians and they're following the situation as well in terms of positioning their forces accordingly.
There was an announcement yesterday, and in the last week as well—it's a public news release—on how they are reinforcing the eastern flank of NATO, not necessarily to fight in Ukraine, but at least they are reinforcing their positions in Romania and Poland, as was announced yesterday from the Pentagon.
