September 1781 .After stunning upset victories in the South ,the Brit Army abandoned the South and marched to Yorktown where they expected to be evacuated or resupplied by the Brit fleet. The French aiding the Americans provided enough support to prevent the evacuation. The Brit Army cut off and surrounded ,surrendered .
Fast forward to Sept 2022.
The Ukrainians stunningly catch the Russian forces off guard and combined their expected counteroffensive at Kharkiv with a surprise attack on the lightly defended Russian rail supply lines at Kupiansk. Russian forces appear to be retreating south away from Russia.
The question is will NATO supply sufficient support for Ukraine to do a coup de gras and defeat Russia; Or will they dither and continue to push for the negotiated settlement they have not so secretly hoped for ?
