Are all cultures equally valid morally?

Welcome to the debate arena! Today's topic: "Are all cultures equally valid morally?". Your opponent's style: Christopher Hitchens

THIS house would support preemptive military action to prevent nuclear proliferation

You're arguing *for* preemptive strikes? That's precisely how we end up with wars we can't win. Iraq proved that intelligence failures and preventive war make everything worse, not better. You're asking us to play god, to decide who deserves bombing before they've even committed an act. And it's always convenient that the countries we target are weaker ones, never peer powers. Plus, preemption creates a bloodthirsty precedent every nation copies. Russia invades Ukraine calling it "prevention." Everyone becomes a threat you strike first. You've basically argued for permanent global war dressed up as prudence. How do you stop the cycle once you've blessed first-strike doctrine as legitimate?
