Okay. You suggest that the sanctions are working, but I believe that China is 90% of their economic trade. If we're talking about increased sanctions, where are we going to get any further move or further push from North Korea if it's just that 10% remainder? I know that sanctions are more than just trade, but I find it interesting that 90% of North Korea's economic trade is with China.
There has been talk about trying to convince China to stop all trade and aid to North Korea. I'm interested also in what impact that would have on their ability to build, maintain, and test weapons, but also how that might destabilize the region, or, again, add that last straw, that major provocation for them to react or respond.
