Feeding and clothing them is a given and International leaders have already determined this in the equation......as well as upgrading their farmers equipment so they can sustain food for their people. But feeding and clothing them is just the beginning and will not address the issues of the two nations integrating.....which go far and above that.
As for being in Russia working......back breaking dirty work and the little money they earn goes to Fat Boys coffers. I see nothing positive about them taking on jobs nobody in Russia will do....except they might have a bit more food.
More food...maybe even at some forbidden capitalistic place like McDonalds...Hear pop music for the first time, make foreign friends. Some NKers will walk into church...all this depends of course on how monitored their actions are by some supervisor or whatever.
Russian church bells alone would be quite the novelty though. They can be heard everywhere. Beats the worship anthems to their “Dear Leader” if you ask me. Its insane to think about how sheltered from reality their lives are.
