The occupier cannot use the excuses of aggression, invasion against them or self defense.
Every action Hamas has taken is in response to the Jews illegally displacing and murdering the Palestinians in 1948 and occupying their homes.
Any action taken on Oct 7 by Hamas is in reaction to the violence of the occupiers. No Hamas didn’t “start it” The Israeli Jews did in 1948. They do not get to have a say in anything.
