After 5 years the arms embargo is lifted, and after 8 years a missile embargo is lifted. I'm really surprised Obama and the Western powers agreed to that. Obama won't see much support for this deal in Congress.
That is actually 5 years longer than the UN sanctions resolution stated. The resolution stated the sanctions would be lifted once they came to the table for negotiations. Also I doubt the opposition will get 67 votes in the Senate, especially with Biden, Kerry, and Reid whipping votes for Obama. So the deal with go through.
