The people of Libya are regretting their 'freedom' after the UK helped them remove Gaddaffi; would North Korea be any different?
No. It would be much worse
Dictatorship "worked" in Iraq because Saddam kept a lid on the warlords and factions.
I don't know if the same case held for Libya.
If thar was the case though, I don't see NK as being anything like the same.
AFAIK, it is not a simmering pot of warring groups, tempered by Fatso.
If anything, it would be more likely to be more like the freed older robots in I, Robot, looking for leadership.
