Remember when Israel just mowed down peaceful protestors after Trump moved the American embassy to Jerusalem? That embassy hasn't been moved back under a Democratic president, either.

This is but one example, under a climate of constant incursion into Gaza and stealing ever more land. That's what Israeli settlements are, after all. They claim land from Palestinians, force them out of their homes, then move in Israeli families.

Anything Hamas does is self-defense.
