"I know that the temptation to engage with extremists can be strong. It may seem to promise stability and quiet. We may hope that by feeding the beast we can gradually tame it. As free societies, we pride ourselves, rightly, on our respect for difference and diversity. But we do a disservice to diversity when, in its name, we tolerate the intolerant. Bitter experience has shown that buying off extremists is a short-term fix for which we will pay dearly in the long run. Instead, groups such as Hamas and Hizbullah must be presented with a clear choice between the path of violence and the path of legitimacy. They cannot have both. And it is this same stark choice that must be presented to the radical regime in Iran."
