However, the sanctions appear to fall short of what would be needed in order to really be effective. One of the biggest problems that I mentioned in my previous comments- all the aid that the U.S. and other countries send to N. Korea. It appears that most of that aid remains intact with these sanctions, particularly the food aid. As I mentioned before... STOP FEEDING THE NORTH KOREANS! With the constant aid the North Korean people are not going to be motivated to take over their government or to overwhelm their borders. The aid gives them little incentive to act.
Much of the food that is sent to N. Korea does not get to the general population anyway. The food aid is instead diverted to the N. Korean military. Stopping the food shipments and the fuel shipments will put real pressure on the N. Korean government. It would also put pressure on China to do more....because China would pick up some of the slack for any food shortages in N. Korea. I say, let China & Russia feed the N. Koreans and deal with the problem of refugees. Those two countries are supporting and protecting N. Korea, so they should deal with it when and if it collapses. China is already attempting to dodge their duties required by the Security Council. And Russia is pretty much in the N. Korean camp as well and probably won't honor the UN Security Council requirments.
I think that this sanctions plan will only have a limited impact on N. Korea.... and Iran is probably not phased by it either.
