On Oct. 7, 2023, Gazans danced in the streets to celebrate Hamas’s rape, torture, abduction, and murder of Israelis. The last time they were so happy was on Sept. 11, 2001. Meanwhile, thousands of their supporters, a motley crew of angry Muslims and maladjusted leftists, celebrated in the cities of the West. Three years later, on the third anniversary of Oct. 7, the Gazans are a defeated people. Yet, the celebrations continue in our cities.
