Politicians get way too carried away... they exist and are strong where they are because they can function fluently in those environments. Like seriously... do you really think IS could stroll across any other country and get away with it? Ah.... no. That is their country and home turf... they have supporters and such there, not so much in other countries. Sure... they can do the terrorist thing and maybe get a handful here and there, but they will be caught quickly and that is the end of that... just like the last bunch of nut jobs. They don't last... old news, then the new kid on the block trying to take on the world.
These morons should get it through their f*cked up heads... the world fights back. The best thing they can do is stay in their country, be tough and big and whatever the f*ck they want to feel like... and shut the f*ck up about trying to step sideways, because that is when they'll get their arse kicked by real armies and weapons.
