Not really helping themselves out, are they?
One has to wonder. Could they truly be that monumentally stupid? Generally speaking you don't **** with Russia. They just don't put up with that ****. If a terrorist sends a Russian a box with a Russian finger in it, the terrorist gets a crate with body parts of the entire terrorists extended family inside. That's pretty much how Stalin operated and spread the fear of God or Allah or whomever throughout the world. You just didn't **** with the Russians, particularly with terrorism. Because Russia just doesn't have a moment's consideration in utterly ******* up your entire way of life because it's "Tuesday" and they have an agreement to get rid of some nuclear arms. They're just as happy to say "**** it, let's dump em in Iran".
I'd be surprised if Russia has become so soft as to suffer such a catastrophic terrorist attack without a few villages disappearing off the face of the earth indiscriminately.
And honestly, for that - I envy Russia. If we were less touchy-feely and more "Hey, let's drop a suitcase nuke off in Tehran" we'd have a ****-ton less terrorism in the U.S. It's not like folks are gonna hate us less. I'm not talking a BIG nuke. Just one that says, "I think you had something to do with attack such and such and now you have 450,000 dead people to sort out." "Oh and P.S. You can't live anywhere within 60 miles of Tehran for 200 years. Sorry."
