Hamas is a grass roots resistance which was born as a result of Israeli oppression. Even if every single Hamas member is lined up and killed, the oppression that gave rise to Hamas would still exist. Another Hamas would rise. After all, there is lieelt enough future for more than a million Gaza residents and Israel has given them every reason to hate Israel. Israelis shouls shy away from the concept of "body count" leading to victory. The American government was obsessed with achieving a high body count in Vietnam but they still managed to lose that war in detail.
