US reviews European troop deployments

The United States is conducting a six-month review of its troop deployments in Europe, announced in June, as the administration pushes for European allies to take primary responsibility for continental defense. The review, led by Under Secretary of Defense for Policy Elbridge Colby, has raised concerns among NATO members about Washington's commitment to the alliance. Washington has circulated a questionnaire to NATO members covering defense spending, basing access, and support for U.S. foreign policy, and Colby is expected to brief NATO ambassadors in Brussels. European diplomats plan to reassure the U.S. of their increased defense efforts, while some officials worry the process may be transactional or predetermined.
