I don't want anyone having those weapons. But they exist, and worse, old ones exist and are unaccounted for. But who should judge which regime should have them, if only some should? Most of us are born into a belief that our people are the best, the right people, and others may also be right... and many are wrong. But regardless, we are most right. As such, we often don't question some things. This is one of them. So should we decide we are the best, most trustworthy holders of such technology and use just about any means to prevent others from getting the technology? However you narrate this, it is an ongoing history which visiting sentient beings would probably marvel at.
