The UN defines genocide, in part, as "deliberately inflicting conditions of life calculated to bring about physical destruction in whole or in part."
This accurately describes Israel's multi-faceted genocide against the Palestinian people.
It is a genocide. It is mass murder. It involves direct violence, starvation, destruction of economic possibility, and it is morally abhorrent.
