Islamic terrorists are evil people--they aren't freedom fighters. They kill innocent civilian people who have nothing to do with their political grievances. They kill men, women and children, young or old, Christian, Jew or Muslim or non-believer of any kind. They destroy historic sites and relics. They make sex slaves of captive girls. It doesn't matter to them whether or not there is any strategic value to what they do. Burning, beheading or drowning people won't bring anyone peace or freedom.
I suppose the Axis considered the US a meddler and bully when we joined the Allies in WWII. I'm sure Germany would have preferred that we never cross the Atlantic and interfere with their plans for the final solution.
Islamic terrorists have no one to blame for their actions except themselves.
