Biden announces new U.S. military deployments in Europe

The big picture: The new base will be home to the first permanent U.S. forces on NATO's eastern flank, Biden announced while speaking at the first day of a NATO summit in Madrid.

• Additional troops will also be deployed to Romania on a rotating basis and enhancements made to the troop deployments stationed in the Baltic states.
• The U.S. will also send two F-35 squadrons to the U.K., bolster defense capabilities in Germany and Italy, and improve naval operations in Spain.
• The administration signaled ahead of the NATO summit that an announcement of troop changes could be imminent, according to NBC News, which first reported the news.

What they're saying: "Today I'm announcing the United States will enhance our force posture in Europe to respond to the changed security environment, as well as strengthening our collective security," Biden said.

• "Together our allies, we're gonna make sure that NATO is ready to meet threats from all directions, across every domain — land, air and the sea," he added.

• At the summit, NATO Secretary-General Jens Stoltenberg said the alliance is "in the midst of the most serious security crisis we have faced since the Second World War."

Flashback: Polish Foreign Minister Zbigniew Rau said last week that the current security crisis illustrated that Europe couldn't defend itself without the U.S.

• For Poland, U.S. engagement in European security is a "fundamental condition of peace in Europe," he added.
