Kissinger said, great diplomats will be “judged in the end not by their cleverness but by their grasp of reality.” The reality on the ground in this 11 year proxy war is that Russia is slowly crushing Ukraine and the longer it goes on, the worse the deal for Ukraine. A look at the map indicates clearly that Ukraine could have had a much better deal in March 2022, yet the UK and the US squashed it in Istanbul.
And the monumental failure of the the Ukrainian invasion of Russia has now ended in ignominious defeat. Ukraine has been ousted eliminating an illusory bargaining chip.
Cease fire in place.
Wait for regime change in Russia—Putin won’t live forever.
Reassess then.
