I hope they will never try to scratch a nuclear power..... 5 tactical nuclear missiles will be enough for them if they decided to fool their self.....
And what will happen to Pakistan after that?
Current Afghanistan is not only an American ally, they virtually America's baby.
Americans brought this new Afghanistan, it government, its army into being.
US and its allies will invade Pakistan seize its nuclear weapons, dismantle its army and install a puppet government in Pakistan.
