By the way, re-reading NT4, I came across a weird line:

"No gunpowder, explosives, poisons, bacteria, radioactive materials, etc. as established by the Second Frankfurt War Treaty (2次フランクフルト戦争条約) may be used. " - NT4 Main 01

This is not explained further or mentionned ever again, and I fail to see how it relates to any of the real life (for starters, most were signed before the use of radioactive weapons in warfare), so I'm drawing a blank.

What do you think it could be? Just one unexplained in-universe reference? Or maybe even the treaty that ended WWIII, the proper name of the Proclamation of Armistice?
