Why do the same people that think America is by far the most powerful country in the world?.......?

A nuclear weapon in the hands of a "tiny petty" country under the rule of hostile and anti-semitic lunatics could cause regional chaos, the destruction of allies (e.g. Israel), and possibly get in the hands of terrorists. We should invade if they are unwilling to concede to UN Security Council demands that they give up their nuclear ambitions.
