True but the U.S. should still stay out of it. Innocent people on both sides will die.
Yes, but can you guarantee Russia, Saudi Arabia, Iran, Yemen, Syria, Israel, Palestine and China will also stay out? Also can you guarantee to me that the jihadists, who have clearly said and it is unequivocal that they wish to see their flag flying over our government and we "Kafirs" will be as slaves.
I don't think you can. So unless you can guarantee that if we, the west, have nothing to do with it and neither do anyone else then I'm with you.
However that does beg the question, are you and I happy to see the bloodbath and genocide that will inevitably occur as radical nutjobs kill anyone in their path who don't believe their crackpot beliefs, wears the wrong clothing (mostly women of course) and anyone who is gay. Personally I'm not happy to watch that with us sat on our hands.
Now I'm sure someone we tell me we were part architects or indeed possibly the main architects of all this, though I think radical regions bear most blame. But we don't have time machines, so we can only deal with what is in front of us.
