“Guarantors are supposed to be uninterested parties, and neutral. “
That’s not what Ukraine is asking for.
They ask for military commitment to turn back any invader.
The ONLY supposed “uninterested party” stupid enough to sign up for that is the US and/or Russia. And they want it codified in treaties.
NO WAY the US ratifies such a treaty.
They will most certainly NOT get what they are asking for.
You said Poland, Germany, and Russia should be the guarantors. Well, right off the bat Russia should be disqualified from that role. If there are to be guarantors, not only should they be neutral, but they have to be able to wield a big stick. That would mean the US, UK, and/or France from the West, and India and/or China from the East. China is as untrustworthy as Russia, and the US under the Democrats is unreliable.
