Here is another reason why a war should never happen.
The Korean Mother would talk about seeing Sang'i Yongsa (= "injured veterans") when she was a child. Soldiers injured from the Korean War would become a class of thugs/beggars, who would constantly cause a ruckus because they were always drunk and screaming about how they gave their lives for the country, only to be looked down upon as cripples.
The Iraq situation now is extremely similar to the Korea situation 50 years ago. Unlike other liberals, the Korean did not think it was a totally crazy idea to invade Iraq in order to establish democracy. It could happen, and the world would be better for it if it did. The Korean, however, knew that it would take at least 40 years to do so -- it took Korea that long. The Korean wonders if the architect of Iraq now has thought of that.
