Alexander,
America and the West allowed this to happen, resulting in a place today just as unsafe from Putin's nuclear weapons. Worse, the THREAT of using is NOW a weapon.
American soldiers are kept off the battlefield because such a mission has zero public trust.
I wrote, "Time for America and NATO to Act?" October 2022, and it remains relevant.
President Biden’s efforts, so acclaimed today, may be considered mediocre in history.
Best.
