Should the US attack Iran? Why or why not?
Jesus, no. Isn't it about time our leaders figured out there's more to foreign policy than trying to get people to agree to our invasions? Even if it were a good idea to invade Iran, we're too damned overextended from the two unnecessary military adventures we're in already. Add Iran to Iraq and Afghanistan, and you're talking about trying to control an area that's bigger, more populous, more religious, no more educated, and at least as violent as the eleven former Confederate states plus Arizona, New Mexico, Oklahoma, Kentucky, Ohio, and Indiana, and that at a time when our economy is in the toilet. It's insane.
King Harold might have beat William the Conqueror at Hastings if he hadn't had to fight Harald Hardrada first, but you've got to recognize the limits of what's possible. King Harold didn't have a choice, but we did, and we still do. Stop the madness.
