Europe (Britain mostly) and the US pushed the newly formed UN to pass a resolution calling for the creation of Israel in 56% of the territory, but the zionist militias actually took almost 75% of the land while destroying entire villages and murdering the existing population. The West continued to support them after that and have been tacitly approving of them taking even more of the land as the decades have gone by. The West is not blameless, but it was very much Israel that did it.
