ISIS is not only a threat the whole world. Its goal is to continue the conquest of Mohammed which aims to take over the world and eliminate all other cultures. It should be taken very seriously because this has happened before and it ended up with 3 greatest empires of Mohammed's time crushed and Islamic empire reaching the gates of Europe and spreading to far east. To the people who fight for this cause life is meaningless. And with American heads being cut off they show they're never going to stop. A coalition of these nations would be a defense against growing threat and a good opportunity to unite with enemies and friends alike for we are facing a common enemy. And after ISIS is defeated there are a lot better chances of solving problems and flaws each nation has than there are now.
