South Korea and Israel

Different Location, Different Propaganda

I see very little difference between South Korea's building a barricade to defend itself against attacks by North Korea and the "wall" built by Israel to defend itself against Palestinian attacks. I also see very little difference between South Korea's threat to "teach North Korea a lesson" by "a limited military action" and Israel's attacks on Gaza to stop the continual rocket attacks and suicide bombers being sent against Israel.

One difference seems to be that North Korea is an independent nation while Gaza is an independent territory. Is this significant? Does the difference that it is oppressed Palestinians verses Jews or oppressed Koreans verses other Koreans change the responsibility for the warring between the two peoples? Can someone explain the differences to me?
