"If building and deploying nukes was easy everyone would have done it by now..."
A non-argument! Those systems are readily available from the Chinese on the world arms market. If the truth were known they've been a part of Saddam's arsenal for some time now.
A lot of countries already have deployed nukes. Even countries like India and Pakistan that have trouble feeding their own populations.
If you will remember your High School History lessons- it was the "peace at all costs" attitude that got us into wider conflicts in both WWI and WWII.
