On not allowing any outside mnt,

From Wise Nano

To clarify the title a little bit, CRN's policy is to send out nanofactories throughout the world as soon as possible when the technology gets here. This policy is to make it politically worthless to build MNT on your own.

I would just like to point out a possible touchy situation that can happen with this policy. The reason for this 'policy' is to keep some unprecedented war from happening, and since CRN has found an ingenious bureaucracy in its 'System of Three Ethics', we can then live happily ever after (that is another debate...and perhaps a hard one to debate till/if we get to that day). However, at the very point where MNT can get developed, many will be close to being able to develop it, and no matter how much logic you try to find to get everybody in line with CRN's program, there will be one or more groups who want MNT for themselves. Here's the problem; CRN's policy is use military ethics to snuff out anybody outside of their loop, but chances are there will be many groups outside the CRN program, so just on CRN's policy, they will commit war almost as soon as MNT is ready to be developed (quite potentially a global war).

So, even before there is MNT for one or even more groups, CRN's policy could lead to war anyways.

However, this does not appear to be a problem unique to CRN's policy. It will be hard to convince any major nation that they can afford to have other nations in the world with unrestricted nanofactories. If arms races are unstable, as CRN has suggested they will be, then the only way to be safe is either 1) not compete militarily at all (requires trust; not feasible in today's system) or 2) preempt any foreign development of MNT.

In other words, MNT development tempts preemptive war anyway; CRN's suggested policy tries to get the major nations on the same side, hopefully minimizing the scope of the conflict.
