To have a dialog with islamic radicals is completely ridicoulous. If you give them some, they will wait a little and then do the same thing shortly....North Korea anyone?....simply said, ignorance breeds.

First, cut off the funds to radical islam by stopping the purchasing of oil and other goods from those muslim countries. Second, ask the government of those islamic countries to take care of their own business or someone else will do it for them in a way that may not end up in a very pleasant way. It is very unfortunate when in some cases military is the only way to solve a problem.
