Hegemony through holy genocide

My concept of God does not allow for God’s blessing of genocide as a means for one country’s hegemony over the earth.

Andrew Sullivan in Exceptional and Unexceptional America []

He is obviously not a fan of the Old Testament God of Deuteronomy and Numbers.

When the LORD thy God shall bring thee into the land whither thou goest to possess it, and hath cast out many nations before thee, the Hittites, and the Girgashites, and the Amorites, and the Canaanites, and the Perizzites, and the Hivites, and the Jebusites, seven nations greater and mightier than thou; And when the LORD thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them

Deuteronomy 7:1-2, King James version

Sounds like hegemony through genocide to me. And it’s not even the worst thing in the Old Testament; remember the Moabites and Midianites?
