Dear Editor,
Recent reports have indicated an additional 1, 400 Marines（海军陆战队）are being sent to Afghanistan in the coming weeks. This means it costs over $1 million annually on the ground over there. I do place a higher level of blame on the policymakers who send soldiers off to kill and be killed in the field. I think the human race needs to think more about killing.
One needs to do the introspection: “Are these wars JUST?” I believe that all of our wars since 1945 have been illegal, under international law as well. I suggest that all your readers examine their conscience（良心）as it relates to the matter of making war. The fact that many soldiers are motivated by a strong sense of duty does not give them some unqualified moral right to support these wars or any other. It’s responsible for all the troops, and the entire population, to determine whether the Afghan or Iraq wars are in accordance with （符合）the development of the state.
I wish someone would give me one or more logical reasons why we are still fighting in Afghanistan and what our goals are. I certainly don’t understand it and neither do many who are more knowledgeable than I.
Outsiders have tried unsuccessfully for centuries to conquer Afghanistan, and we seem to be no more successful. We are trying to develop a stable central government, but the country is badly divided into ethnic and tribal groups, and the current government is corrupt（腐败的）. Moreover, we are apparently regarded as undesirable occupiers by many of its people, most notably the Taliban.（塔利班）
If we are to continue spending billions every year in Afghanistan and killing hundreds of our people and many of theirs, our government must provide us with a reasonable explanation of why we are doing so and what we can expect to accomplish.
