Spanish Prime Minister Pedro Sánchez suggested that the fact the four leaders represented all sides of the political spectrum - with Spain and Malta governed by centre-left parties, Slovenia by a Liberal party, and Ireland by a centre-right party - showed there was broad political consensus that the recognition of Palestine is necessary for any future peace process.
Although the European Union supports the so-called two-state solution - which would deliver statehood for Palestinians - and is the single biggest donor of aid to Palestinians, it has not yet unanimously backed the recognition of a Palestinian state.
Most of the world recognizes Palestine. It is really the Western Europe, North America and some other close Western allies which do not. So it will not stop Israel. The way to do that is by force. The good part is that the West is changing its mind on the topic a bit. It also seems like Bibi might not get reelected.
