The thing is... Iran could stop all it's production of enriched uranium and nuclear material. The west is happy and allows them to trade again and Moscow is happy because they have someplace to ship their uranium and nuclear shit too.
It will be controlled (by Russia) and Iran could still run it's nuclear plants. I genuinely don't believe the current Iranian government would use nuclear bombs on any country. If it had still been Ahmedinejad, then yes, I would be a little more worried but still, every world leader knows better than to launch a nuclear missile into another country. The new, softer, Iranian government I believe has no intentions whatsoever to go to war with any other country.
I think it's all still the effects of years and years under the rule of that nutjob.
Obama is doing a great job internationally speaking of walking a softer line. Iran is now 'free', Cuba is welcome again. All of this is a good thing. The Republicans don't like it. They still see Iran as a threat, they still see Russia as a threat, etc. etc.
Israel is upset now because they wanted full and utter capitulation of Iran and the immediate stop of that countries nuclear programme. Now, in regards to my recent posts, I'll try to keep it civil but Israel has become one of the greatest factors of unrest in the middle east, aside from IS of course. Netanyahu's warmongering is only matched by George Bush so far and his landgrab is only matched by Putin.
