Israel being critical of Spain doesn’t mean they’re involved in dumping migrants over the border.
When the criticism are ultra specific yes it is very legitimate to believe Israel is involved
The “paid part” is the implication when the conspiracy is that the Moroccan military is dumping migrants across the border as dictated by Israel. They wouldn’t be doing that for free and implies that the Moroccan government is complicit as well.
So it is just your assumption that people said . Like the Ynet article that is spreading israel narrative mention because of the abraham accords, the Moroccan dictatorship is helping Israel destabilizing Spain. The video literally show someone in Morocco's Royal Gendarmerie clothes. Unless Morocco provide evidence that person is not a real Gendarmerie person they have to show evidence of the man identity
Literally anything that proves A) this was orchestrated by the government, whether that’s the Moroccan or the Israeli one and B) an actual concrete link between the wave of migrants and the Israeli government. That seems to be the bare minimum required to even entertain a conspiracy theory like this. But I honestly think the conspiracy is a little ridiculous on its face (Morocco wouldn’t go along with this) so I personally am not actively trying to prove anything here.
