As It Is The Munich (in)Security Conference.

The Fall of Saigon is not an accurate parallel. For the US/UK-led NATO disaster in Afghanistan.

US troops withdrew from Vietnam in 1973. The 1975 Fall of Saigon was just the evacuation of the US Embassy. Technically US territory.

The more accurate comparison is the 1940 Evacuation of Dunkirk.

It is exclusively the benevolence of the Taliban. That stopped it turning into the Battle of Dien Bien Phu.

Despite the best efforts of the absolute Fool of Kabul.
