Idiot....who says their first strike takes out the entire USA?
What if they only lob 5-10 ICBMs that take out some ICBM sites, DC, LA, SF, NYC, Chicago, and Detroit....do we surrender because you didn't want to have nukes in reserve to shoot back???
Russia is the only country that can wipe the USA off the map "right now" but China is working on it. But of course, idiots like you are focusing our numbers against Russia while ignoring the Chinese standing behind the door with their nukes.
First of all, if a country launches nukes at us and DOESN'T wipe out the entire USA, they're ******* stupid. Second, for someone who claims to know everything about everything regarding defense, that was a pretty stupid answer.
If any country on the planet launches ICBMs at us we'll see it coming well in advance. Retaliatory ICBMs would be launched from those targeted sites. We only need enough nukes to wipe out the planet once, anything more than that is an unnecessary overkill.
WE CAN DESTROY THE PLANET MULTIPLE TIMES OVER! It doesn't matter what country develops what, or how many nukes they have, we have it covered. We can dismantle some nukes and still overcompensate for neocons' small penises.
