The withdrawal of 25,000 troops is disabled. The Pentagon changed its mind.
The US has changed its plans to reduce its military presence in Europe. According to Bloomberg, about 5,000 of the 80,000 American troops will return home, mostly from Germany. NATO's eastern wing, meanwhile, may be strengthened: countries bordering Russia are willing to pay for it.
The Pentagon also faces other constraints: The law prohibits keeping US troop levels in Europe below 76,000 for an extended period, and the new Democrat-controlled Congress will follow even more closely.
And by the way, when Putin demanded in 2022 that NATO return to the 1997 borders, the number of American soldiers in Europe actually increased instead. And it was Joe Biden who made it happen.
