Why go to Iraq?

It is not for individual soldiers to refuse such orders. A soldier has a duty to refuse unlawful orders, but individual soldiers simply cannot reasonably argue that a war itself is unlawful; that is a question that must be decided at the highest levels. If individual soldiers may decline to participate in a war, that is an invitation for mob rule: we agree to serve our country, not to serve when we agree with the decisions our leaders make. The system would not work otherwise.

Army Major Andrew Olmsted explains why he is going to Iraq.
