The word is these are people who lived in France, went to Syria, got trained and returned to reign terror.
I've always been for staying out of the business of other countries and not policing the world, but I have reached the point that serious measures now need to be taken against ISIS or this will just continue in countries around the world - including the U.S.
At this point, it's time. We need to put together a multi-national force, have an up and down vote in Congress to declare war - and declare war against ISIS and go all out in Iraq/Syria. Full invasion. Scorched earth. Wipe them out - and then leave. They come back like cockroaches, go back in and wipe them out and leave. Repeat and rinse until they decide to live peaceful lives.
