"We have a nonaggression pact already. Anyone invading is already ignoring the rules. You know what I mean?"
"Woah woah woah. You're basing almost your entire defense on nukes? Bad move. What'll you do if you're invaded?"
"They said 'major part,' not 'entire'"
"And I said 'almost,' selectively stone sonics."
Hmm. The New Order may be willing to forgo nuclear use, providing said armaments remain in our possession for their possible uses in the Great Plan.
"Again, 'woah woah woah.' What is this 'Great Plan' and why does it need nukes?"
