I don't know what that is supposed to mean, as far as I know he hasn't been asked to beg or been berated like this by any other nation but the United States.
Your suggestion is that European leaders don’t believe him, which would be counter to every public statement they’ve made.
He’s getting support from European nations. The US is capable of more support, hence asking for it. This isn’t complicated, I have to suspect you know all of this and are being disingenuous anyway, and I cannot fathom why.
