Let me see if I have this straight. Our good friends the Saudis are airlifting weapons to ISIS, our enemy in Iraq, and our mortal enemy Iran is airlifting weapons to our friend, the Iraqi government. And there are people who seriously want us to get involved in this mess? Which side?
If it's not confined to those who choose to participate, Israel will be involved against its will. Then it will take agressive retribution. If that happens, hopefully it will stop there.
To me it is totally irrational to fight over religion. My god is better than your god and I'll kill you to prove it. Idiocy.
