CBW,
To be fair, I was making the legal case, not the moral one.
Why? Because that was the question asked. If you at the first line of the thread, the question was, "Is sending our troops into this war an illegal order".
If you want to move on, change the subject, and discuss moral arguments, then fine. But I believe I made my case over the question asked. And in terms of the consequences, the effects of disobeying a legal order can be harsh.
The military do not have the freedom to make decisions based on their own moral qualms.
