Sadly, we have nests of carefully tended crows in all Western nations, including the US. And they're not just mad about something 600-800 years ago; Islam has been violent since its very beginnings, which would be about 1300 years ago. It just took it awhile to bring that violence out of the ME and into Europe.
If we have to take military action we have to do it soon. I don't see anything else working. We spend so many billions of dollars and sacrifice so many lives to make sure Iraq doesn't or didn't have any. But if next door iRan acquires them after all this then everything would have happened in vain.
