Once again, you fail to understand 1 bullet can only hit a single target. The 800 lb gorilla should have far more nukes (yet reality has shown this to be false, because the 800 lb gorilla is horrible at this game)
The 800 lb gorilla should be able to team up and lock down people, yet we have shown that they are incapable of doing so. We have ZI'ed people in a day, people who outgunned us, people who should have destroyed us. This wasn't because we could hit 3 people, but because we know how to hit our targets more optimally.
The fact is, we play smarter, are better with our strikes, and we know how to hit things for the biggest impact. The nukes being able to be tossed at 3 things is a side note when you consider the war once nukes are gone. We show that strength at the low end, where we don't have nukes, and will continue to show them long past when the last nuke is fired off.
