“invade their lands and give them a choice: convert or die”
That sounds to me like judgment. I don't recall Jesus teaching that path.
Let’s recall that the comment Anne Coulter made was closer to, “invade their countries, kill their leaders, and convert them.” “Convert them” is exactly what Jesus taught when He said to go and make disciples of the nations.
We may quibble about killing their leaders, but death was a penalty for many of the laws that Jesus came to fulfill. Indeed, His objection against stoning the adulteress was not that the penalty was too sever, but that there was no one qualified to administer it.
Are you saying we shouldn’t be killing the leaders of terrorism?
