Let’s put it this way, we are bombing ISIS in order to save innocent lives and to prevent this so called Caliphate from over-running our friends, the Kurds.
If it just so happened to benefit Iran, so be it. This is temporary.
We don’t have to let our guard off when it comes to Iran.
Nothing’s temporary there. Iran is one of the “pretenders” to the Caliphate also, remember. The real enemy is the Caliphate no matter how many heads manifest.
