This week Russia agreed to sell $1 billion worth of weapons to Iran. Many American policy experts are trying to understand if this is part of some new Russian foreign policy. They are right to ask - why does Russia sell weapons to an Islamic theocracy that has armed Chechen terrorists and other Jihadists around the world?
Abu Omar Mohammed bin Abdullah al-Saif would've answered that it's because Allah wants Russians to help the extremists with their Jihad. But after a life devoted to murdering civilians and children, Mr. Omar, etc. has been killed during a successful operation conducted by Russian forces. I'll try to answer for him.
Russia is well-known for corruption and kick-backs on business contracts. RussiaBlog has reported about President Putin's "gifts" and the bribing of the head of Rosvooruzhenie, among others (Rosvooruzhenie is the government company that deals with weapons sales).
I honestly believe that this is no realpolitik or other strategy on the part of Putin's administration. The truth is that no one is in charge to prevent such exports; no one is actually considering what is going to happen to the missiles Russia is selling to Syria and Iran.
1) there are individuals who profit from certain sales operations;
2) these individuals have nothing to do with foreign policy decisions;
3) the only competitive Russian product is weapons;
4) margins and kick-backs on Russian weapons are very high;
5) there is no working government system to control complicated foreign policy processes and these corrupt individuals.
So, don't worry, Russia doesn't intend to equip Jihadists with weapons which will be used against US, NATO and Russia itself, however, it's doing it anyway, because at the moment, Russia is a very confused, disorganized and mismanaged country. So if you are afraid of Russia -- please don't be; though if you are afraid of the terrorists, just be afraid, there's nothing you can do about it at this point.
