NATO allies are moving closer to sending troops into Ukraine to train Ukrainian forces, potentially involving the United States and Europe more directly in the conflict.

Facing a manpower crisis, Ukraine has requested NATO assistance to train 150,000 new recruits closer to the front lines.

While the U.S. has so far declined, Gen. Charles Q. Brown Jr., Chairman of the Joint Chiefs of Staff, indicated that a NATO deployment of trainers seems inevitable.

The U.S. remains firm against sending American troops into Ukraine and has advised NATO allies similarly, though leaders like France’s President Emmanuel Macron and Estonia’s government have suggested they might support such deployments, DNYUZ has reported.

Previously, the U.S. and allies have trained Ukrainian troops in Poland, Germany, and the U.S., but logistical challenges and the current training’s insufficiency have prompted discussions about moving training closer to the battlefield.

Training in western Ukraine, such as in Lviv, is one possibility, though this area has been targeted by Russian missiles.
