Iran is hiding something gravely dangerous by building so many underground and so vastly arraigned nuclear proliferation facilities. I think that it would be funny in that when they go to test one of their nuclear arsenal weapons that they blew themselves up in the blast. They need to be transparent like NK is trying to be.
"Iran is so insincere... but why?"
It's the same reason that torture doesn't work-anyone will say anything to avoid being hurt-and our country is dead-set on going to war with Iran.
And do you really think NK is transparent? Every few years we write that guy another check and he calms down again.
