Pentagon reduces US NATO involvement

The Pentagon says it will reduce U.S. participation in NATO advisory groups as part of President Trump's strategy, affecting about 200 military personnel and nearly 30 alliance organizations. The news concerns groups on energy security, maritime operations, special operations, and intelligence. According to sources and experts, the decision is linked to worsening relations between the U.S. and Denmark, as well as other allies, over Greenland issues.
