If you are Matt or Glenn, or stalwart followers of either, then this line of thinking is strictly verboten.

(Which is funny because I think Glenn’s express aim is to do everything he can to undermine American hegemony. Shrug.)

Then you wouldn't have thought enough about it. Look at what happened when the USSR collapsed: the world became less stable and nuclear tech and scientists found their ways in unsavory countries.

There were some civil wars or frozen conflicts that are still a pain today (Transnitria, breakaway republics in Georgia, the whole Ukraine thing, and more recently Azerbaijan vs Armenia).

When the enemy has nukes you want him to be a known quantity, stable and predictable.
