Top NATO commander joins briefing on review of US defence engagement in Europe

BRUSSELS, Sept 18 (Reuters) – NATO’s top commander, US Air Force General Alexus Grynkewich, took part in a virtual briefing  on Friday for Pentagon policy chief ​Elbridge Colby on potential approaches to a review of ‌US troop deployments in Europe.

US Defense Secretary Pete Hegseth announced a review in June of America’s troop deployments in Europe and threatened to withhold some US dues to NATO if “free riding” allies did ‌not ​meet their defence spending commitments.

Grynkewich took ⁠part in Friday’s meeting ⁠in his capacity as head of the US European Command “as Europe continues to take more and more responsibility for its defence, and as the Alliance ​continues to strengthen and transition to ‘NATO 3.0′”, a NATO spokesperson said.

A document seen by Reuters shows the review ⁠will create at least four ⁠sets of options for Hegseth, with ​Friday’s briefing contributing to shaping the possibilities on the table.

Hegseth ​told defence ministers at NATO headquarters in Brussels ‌in June that the review would last up to six months and include consultations with Congress, which has legislated a minimum number of US forces in Europe.

While he did ⁠not explicitly say the review could result in reductions of the 80,000 US troops deployed to Europe, he stressed the goal ⁠would be ‌to prompt the continent to do more ⁠while ensuring the US military would be ​able to ‌meet its global commitments.

Hegseth also slammed ​allies who ⁠did not support the US during the Iran war, after some denied Washington basing and overflight rights for war-related activities, and said the review would ensure these rights were assured.
