@giujohn,
No, he can't - unless he's willing to kill millions of people with his order. But wait; this 70 year old child might just do that. He's not mature enough to understand the destructive power of nuclear weapons.
He already said, if we have them, why can't we use them?
A mad man ready for MAD.
Don't forget; this is the same guy who is willing to destroy the family of any terrorist; to kill them. That is against international law.
