Yes they have, well longer actually. Iran has been fucking around too much for too long, and bullshitting all the way. Just 3 weeks ago Irani militants were caught by British soldiers smuggling weapons and materials to develop nukes over the border into Iraq. Then the Irani president closes the borders from Iran to Iraq and claims they were never involved. Bullshit.
Iran also thinks it necessary to go forward with massive uranium enrichment projects for the last few years, which is step 1 for building nuclear weapons (and thats about all you can do with it too so it's kind of obvious). The UN say "Hey Iran, stop being stupid and cut that shit out." Iran says "What shit? We are just messing around thats all." The US and UN have formed agreements with Iran for them to halt the sudden rapid production, but Iran has been dragging their feet for months. This is a bigger problem than most have mentioned. The US is showing 2 barrels, and hopefully this preperation makes Iran halt production before the entire Middle East goes into a race for nuclear power just for the sake of safety, like another Cold War. It really sucks when a country is forced to develop nukes for defense just because some dumbass Iranian president decides the start pointing them all over the place.
I have many people over there right now, so I am going to respect what they are doing until I have to go. Hopefully Iran will back down and this won't escalate.
