In the first article by Reiss, he has a more non-violent approach to solving the North Korean nuclear testing threat. He wants to try to talk again with North Korea. He says to do this, however, the U.S. must gain a better relationship wit both South Korea and Japan. He says to do that we must invite South Korea to the PSI. This will bring three powerful nations to the table against North Korea.
In the article by Zelikow, he suggests a more hands on approach. He says that talk agreements have failed. Now it is time to get to work and give them an option. Stop or be attacked. The two articles coincide with the issue of international support. Both authors feel that the support from other nations is critical in stopping North Korea.
