Ukraine alone cannot do that. That's why Europe should enter this war.
Your "Coalition of the Willing" is a sorry sight.
It willingly admits its own impotence. Starmer and Macron say they will only put boots on the ground, if there is an American backstop.
What a "castrated" thing to even admit out loud. Personally - I would be ashamed to say such a thing.
It's also absolutely retarded.
Why retarded? Because supposedly this initiative was supposed to display European "strategic autonomy". So autonomous, you need the US Air Force to provide an umbrella over your troops.
As an American, I would be irritated to see such a transparent way of trying to pull my country into this entanglement through some kind of 11th hour, back door attempt. As an American, I would say - "I told you ten thousand times I don't want to be involved, what the hell is this nonsense?"
