Ambassador, I don't think you understand somethings here.
1. NAPA enshrines the right bear Nuclear Arms to prevent nukes from being banned by the WA. Without NAPA, all that is needed to ban nukes is 1 resolution. With NAPA, a repeal and a resolution are needed. It's a safeguard.
2. There is no reason to repeal NAPA except to pass a ban on nukes, thus the assumption that you intend to ban nuclear weapons.
3. Your concern in the repeal text over the use of nuclear weapons is addressed in another WA resolution.
