If we give up one third of our nuclear stockpile we still have enough power to destroy the ENTIRE world 6-7 times. The Russians will have the same capability.Paper tiger,no way. If, God forbid we are nuked it will be by a terrorist group not a country. That's what makes things so difficult. Terrorists have no country. Many of them are enemies in their own country.If we find out that they were from Pakistan do we nuke them? Nuclear weapons are a deterent to countries,they are not to terrorist groups.
