The 40’s was the standard “zionists get israel for real this time” after England got its butt kicked by the very same folks it helped in the teens.
But that’s irrelevant to the point that nothing, ever, makes a genocide ok. Stop pretending it’s not just because the fascist and gaslighting zionists claim it’s “not a genocide we promise.”
England did a genocide on the Irish. Zionists are doing on in the Palestinians. There have been plenty of US backed ones over the years too.
Any nation state who says “they’re not doing a genocide” .. totally is.
