This academic exercise of 'economic embargo' that the Administration is thinking about is only doomed to failure, IMHO. It will be as porous as the slices of Swiss cheese I snacked on earlier today. But let's let them try it for awhile at least until we can judge the results and move on to the next options....
The only things that will work w/ North Korea and Gen. Kim Jong il probably are as follows:
--Assassination/Coup d'etat and regime change by purely internal elements but supported to external forces
--A stream of N. Korean refugees into China into UNHCR refugee camps causing internal collapse in Pyongyang
--A propaganda campaign of hijacked N. Korea TV/Radio frequencies and balloon drops with leaflets/food to reach the people directly
--And finally, a strategic strike on N. Korean nuke plants and missile production/launch facilities, with probably a larger invasion war.
Scouts out! Cavalry Ho!
