I think I foresee a solution in all this:
Attacking forces are Sunni, while Iran has pledged to send many fighters “to help the Shite cause”.
Did you enjoy the Iran/Iraq War..? I did.
I think we might see another war, but this time Iran/Proto-Al Qaeda —not so bad.
I hope each sides kills VERY MANY of the other.
If Iran enters Iraq what will Saudi Arabia do? This can get really ugly.
