Another Iranian nuclear scientist has been assassinated in Tehran and a familiar pattern is emerging: Weeks before a new round of talks, all sides escalate and provoke, mainly to improve their negotiating position at the upcoming talks.
The West has adopted new sanctions and is pressing for an oil embargo. The Iranians, in turn, has started enrichment at the Fordow facility and has warned it will close the Strait of Hormuz if the West proceeds with an oil embargo.
But there are also actors that escalate at times time not to strengthen their position at the talks, but to scuttle the talks. The attack on the British embassy in Tehran late last year was partly motivated by the desire of one political faction in Iran to undo the talks. Yesterday’s assassination of another Iranian nuclear scientist was likely conducted by a regional actor who prefers a military confrontation with Iran over a compromise that would permit Iran to retain nuclear enrichment capabilities, even if it doesn’t build a bomb.
Indeed, in late November 2010, nuclear scientist Majid Shahriari was assassinated in an identical way as the killing of Mostafa Ahmadi Roshan yesterday. That assassination took pace only seven weeks before a new round of scheduled talks between the P5+1 and Iran in Istanbul.
Yesterday’s assassination also precedes the next round of talks with a few weeks.


I wonder just which of the four countries are responsible for this cold blooded murder. Is it Great Britain, France, the U.S. or Israel? Or are these four countries working in concert? It's hard to tell these days. This needs to stop!!!
That it does Onesmallvoice, that it does!
WHY?
if obama want to win the election 200% he must attack iran now and show the world that this dark evil empire can be stopped. thos evil thugs shiia of iran are helping the terrorists orginization hizboallah and syria thugs bashar al kalb and nori al maleki of iraq evil helping evil. iran has the weapon of mass destruction , sanction will be not good for those thugs,
Here goes another blood thirsty, mindless moron who has never seen military service let alone been in a war. When are people like these ever going to learn that there is no glory in killing people? People like these are truly sickening!!!
Ditto
The problems you are talking about are not a threat to the US. We need to start controlling our own foreign policy!
Ditto man
I am not sure under which rock you crawled out, please do us all a favor and CRAWL back under it. Thank you "kindly".
Good. Then the assasinations will continue!!!!! Hahahahahahahahaha.
Remember what goes around, come around. Careful what you wish for!
No doubt we in the West puzzle over who the perpetrators are, especially when Iran is pointing its finger at us.
Yet ordinary Iranians are mainly preoccupied with the country's economy. Inflation is their biggest concern. This no doubt keeps the government more awake than the death of a scientist.
According to International census their economy was not effected by the global meltdown we are in, they have gone from 35 million in 1979 not manufacturing ANYTHING (carpets only) in Iran, to close to 80 million population and they have industrialized. Inflation is definitely a drag on their economy (specially as of late) but to make this statement about them and how they cannot sleep and FORGETTING we're in a deeper hole does not make us feel better. BUT NICE SPIN!
So since no one has named them, let me tell you who did it- Israel's Mossad. I don't know why they aren't explicitly named in the article, maybe for fear of reprisal? Israel has an interest in removing Iran's nuclear capabilities forcibly, since they recognize like everyone else that Iran will never give up that program through diplomacy. It's unfortunately Israel that would bear the risk of a nuclear armed Iran, so they're just acting in their self interest.
Most definitely Israel. This is how they do it since the first time they did it and killed Lord Moyne in Egypt. Amazing how this is considered an act of heroism by them, but if an Iranian dared do it to one of theirs he will be considered a terrorists by them and the west alike. And so it goes
Good point, our side isn't always in the clear right like we love to imagine.
It is good to see finally we the American Public are starting to wake up from our DEEP slumber, before we lose ALL CREDIBILITY in the world supporting a pariah state like the one in Israel. I just hope it isn't too late.
How does one abbreviate the word "assassination"? Hahahahahahahahahahaha.
Booth.
"How does one abbreviate the word "assassination"?" - I'll tell you how; hold your breath for 15 minutes it'll come to you!
Remember, he was MURDERED – he didn't "die" or "get killed"........when some joker places a limpet mine on the door of your car and kills you.........that is murder.
And soooo cowardly!
Where was our concern when Pakistan and India got the bomb. There is a war waiting to happen!
Shoot and kill those shiia Muslims thugs, why USA are cowered toward Iran, that's why we must elect the republican again, those dark evil empire of Iran must end they must be destroyed.
UK, USA, France, Germany, Italy and all the NATO force must start attacking now before it is too late, we must attack 24 hours round the clock, all target , command and control, radars, soft targets, all boats and ships, all submarines, all the reactors, all the government building, dams, QUM, ayatollah house and compound, destroy those evil
PLEASE TAKE YOUR MEDS! Sheesh!!
Iran already assassin ,killed, murdered more than 9000 Iraqi scientists kurds, Sunnis and Christean top scientists in Iraq killed by Hezbollah, Mahdi militia , sadder army, asyeb ahl al haq, Hakeem and al qodos army,Bader army , all those are supported by Iran , Now Iran asking Iraqi shiia to send 1 billion dollars to Syria and more than 100,000 men to go to Syria and kill Sunnis, kurds and others ........
A 'regional actor', huh?
Israel wants them in the stone age – they are the Nazis of the Mid East now.
Go to youtube, and search for "Leon Panetta" and Iran. You should be able to find two things of interest to you. 1. Leon Panetta admitting that he does not think that Iran is developing nuclear weapons. 2. Leon Panetta saying that the USA had nothing to do with the assassination of Iranian nuclear scientists. What is so great about #2? Watch his body language . . . . he is lying like he**. While he is saying that the USA did not know anything about it, he is not shaking his head left and right, but noidding "yes". Besides that, which coutries have participated in more wars in the last 50 years, the USA and Israel or Iran?
kooshy,See my poerivus comment to Eric. I see no room whatever for any input from Israel regarding the proposed arrangements.
My wife and i were absolutely joyful that Michael managed to round up his inquiry by way of the ideas he received through your blog.

If you find Chelsea within the lineup, which include those of this on-loan gamers including Lukaku, as an example, you could find away, Chelsea palm resource can be hence abounding. Cheap Soccer jerseys They need an outstanding goalkeeper with mortgage loan with Atletico The country (Courtois), I got explained to this he is just about the best goalkeepers throughout Europe, and also within the Chelsea goalkeeper job, Cech and also Turnbull are great.

And also Everton, including Bynes, Cole can be very competing, throughout his or her provide express, as a minimum might enjoy for two years with the major. When Mourinho stepped into your Standford conduit gate, he will find some familiar amiable confront, and this are going to be his or her reconstruction of an different time with Chelsea.
