First of all Oh clueless one, that is not what is happening here. We're dealing with fanatical muslim TERRORISTS who think it's OK to kill anyone they feel like. All in the name of Ala. Big difference!
Second, if you want to be petty about this, and I suspect you do, there are very few chunks of dirt in this world that are not occupied by the original owners. Including your little island. So maybe we should give it all back? Or maybe you should simply get over it!
