Biden: NATO more united since Ukraine conflict

STORY: Biden pledged ongoing support for Ukraine, including $800 million of additional weapons aid for Ukraine, to be announced in the coming days.

Speaking at a news conference in Madrid at the end of a NATO summit, the U.S. president welcomed the additions of Sweden and Finland to NATO and said the alliance would defend "every inch of NATO territory."

The United States is changing its force posture in Europe based on threats coming from Russia after its invasion of Ukraine and other directions. Biden confirmed the U.S. will raise the number of destroyers in Spain to six from four and said Washington will send two additional F-35 squadrons to Britain and establish the 5th Army headquarters in Poland.
