Yes, the “all Palestinians on the planet” bit was indeed extreme. They don’t really care about Palestinians in, say, Michigan. It’s the ones in Gaza and the West Bank they want to get rid of. Ideally with “simple” ethnic cleansing and expulsion, a second Nakba, like their high ranking government officials have been saying. But in less than ideal situations, like the current one, their low ranking officials, military officers, prison guards, soldiers etc have already shown they are perfectly capable of hearing the genocidal dog whistle.
