Iran's Nuclear Submarine
As the nuclear weapons and enrichment talks approach again in Moscow, Iran states another need to enrich uranium to weapons-grade purity of 90% or more. If you recall, months ago, they said it was for peaceful intentions, namely, for nuclear reactors to generate electricity. The West did not "buy" that very much because you do not need to enrich to 90% for that. Now, Iran claims it is building a nuclear powered submarine. Iran reminded everyone that producing such a submarine is peaceful and civilian and every nation has that right.
According to intelligence, Iran is bluffing because it has no capability to do so and the announcement is just to give them leverage at the talks in Moscow. Iran is now enriching to 20% for research, and the odd thing is, a nuclear powered submarine could operate on 20%, but most Russian and US nuclear powered subs operate using 96% nuclear fuel.
The West wants to freeze Iran's enrichment at 20% purity and ship out nuclear fuel to other countries and shut down enrichment altogether. So far, the only agreement reached after two meetings and several months is to meet again.
