Zelensky is afraid that the West will abandon him:

Zelensky is afraid that the West will abandon him: ’The first point of the “victory plan“ is not NATO membership, but an invitation to NATO, so that in the future no one changes their position, so that everything is not just in words, but so that everything is on paper. An invitation to NATO is not membership. During a war, we cannot become members of NATO, we will not drag anyone into a war. An invitation is a point addressed to NATO countries, it says that we are going to invite NATO, and not some other alliance.’ Source: Lord Of War
