Note: Both Russian and Iranian officials claim that S-300 missiles are a type of defensive weapon and delivery of this weapon to Iran is not the violation of the UN arm embargo imposed on Iran. In this respect, i should say that everybody knew and know that S-300 is a defensive weapon. The important point is how on earth suddenly out of the blue, Putin has decided to lift the ban in this matter at the present. The answer to this issue might lie in the secret triangle negotiation between USA, Iran and Russia. By this move, Obama administration has shown its honesty and loyalty to Ayatollah Khamenei and at the same has given Iran a full security guarantee in case of a possible unilateral Israeli air strike against Iran's nuclear plants.
If my prediction in this matter would be true, this event could be the most dirty and scandalous trick of Obama administration; worse than Watergate Scandal for President Nixon.
