Spoken like a true racist, grouping up “middle east conflicts” as if it was a single entity.
Pretty easy actually, Palestinians were there living their lives and having a sense of nationality as Palestinians since the latter years of the Ottoman Empire. Zionists decided they didn’t care about that, decided they deserved their ancestral homeland, and western countries helped them militarily to relocate hundreds of thousands of people and murder tens of thousands on top. It’s almost quite literally that easy.
