To seek the truth in this you must find out who, or what, benefits from ISIS expansion/solidification, and Iran having a verifiable nuclear capability...
Avoid (for now) trying to figure out a way to stop this, and it makes that discovery easier...
the IslamoNazis will be a lot easier to stop or slow down now than later, after they control even more territory (or terror-tory)... and after they finish their ICBM nuclear bomb arsenal
