That's one strategy. I would counter with the suggestion that if the US/NATO had entered into the Ukraine/Russian war full-force immediately after the invasion began, nuclear weapons would have been used. It would have started with a couple of small tactical nukes over Ukraine, but would have quickly escalated to a more widespread exchange. No telling how far it would have gone, but I guarantee you we would be living in an entirely different world had your strategy been used in Ukraine.
I fully support your strategy if you are going to war against a country without nuclear weapons. But countries with nuclear arsenals require a different approach if you don't want entire cities wiped off the map.
Its true there was always that risk. And yet we’re still helping a nation with probably as much technology as they can utilize and Russia has still stood against it and ground it to a stalemate. So now where are we? What additional weapons can we give to Ukraine to break this impasse?
Entering now is even more dangerous I. Someways as far as nukes are concerned.
Both sides are hyper committed to the war and backing down is probably more difficult than early on.
Care would have had to be given in how we approached aiding Ukraine directly.
Air cap early on, nato controled artillery, special forces sappers and recon units.
We all know that depending on the war and nations involved perceptions of the war on both sides is virtually as important as the armies they can field. Especially today.
It’s becoming a Vietnam with mushroom clouds on the horizon.
So roll in with specialized units and brigades to focus and concentrate damage to strategic locations.
And that raises the whole ugly problem of command and control arguments and cooperation. Would any of the four large nato members submit their troops to another’s control in a war in Ukraine.
So we try and negotiate it. Hope those mushroom clouds do not grow on the horizon and we keep sending weapons to Ukraine till they can no longer fight. And be assured their is always point in time that no nation can go on any further when hope remains to distant. The Ukrainians are brave beyond question but there are always limits.
And what will the hawks in the west be demanding if Ukraine collapses next fall internally.
