Should the Japan Self-Defence Forces join international peacekeeping operations?
I think the Japan Self-Defence Forces has already joined international peacekeeping operations well enough, therefore my answer to this question is "No." They don't have to step it into further, I think. I'll share two reasons I have.
First, if they expand their international peacekeeping operations, it means their lives will be at risk. They'll be sent to a border dispute, and of course they'll have to deal with worldwide terrorism. We shouldn't forget that each member of the Self-Defence Forces has a family. They have a father, a mother, children and relatives. Any nations need to protect all of its citizens and shouldn't send anyone to a danger zone. I have a friend in the Japan Self-Defence Forces. No matter what happens, I don't want to see her be sent away. I don't want her to kill anybody. I don't want to see her mother cry. I believe her task should be to protect our country. That's why it's called "Self-Defence," isn't it?
Second, it's wonderful to work on peacekeeping operations, but who judge which is correct and which is wrong? Can we be fair to everybody? There are a variety of perspectives in the world, and anybody has a reason why they get upset. Peacekeeping operations have a possibility to generate another conflict. Japan shouldn't be involved in such a situation, I think.
Of course, Japan has a responsibility to keep the world peaceful. What we can do is not to join, but to assist like we have done, such as the supply of food, medical aid, funds and so on. Staying neutral is a must for the Japan Self-Defence Forces to avoid another conflict and somebody's death.
