War or Peace?

I think a country/people should be allowed to keep enough to defend themselves with.

But if every country was disarmed of weaponry then they wouldn't need to defend themself.

That would be considering every single country agreed to not build weapons in secret, that wouldn't be possible either.
The Germans did it in WWII, and the Syrians managed to make chemical weapons to use on citizens, so honestly I don't know what else to say.
