God gave the land to the Israelites. Dawkins calls this immoral but he has no rational basis for doing so. God created the land, He created all human beings, He decides when each of us will die. Dawkins implies that God didn’t give someone something they were owed but Dawkins does not explain why God owes anyone anything.
I didn't read Dawkin's column and there was no link to it in the article, but the quoted claim was Craig makes an argument to justify mass extermination.
Clearly Craig did that and you just did as well.
Saying it's OK because God can do whatever He wants and we don't know his ways is the quintessential apologetic argument.
Dawkins appears to have been exactly right regardless of whether Craig's rationalization makes sense or not.
