LGen Romeo Dallaire, former senator and now head of the Child Soldiers Initiative at Dalhousie University has stated without equivocation that Khadr was a child soldier. Your opinions are personal and not based on facts or the UN Protocol that was signed by Canada on child soldiers.  https://www.childsoldiers.org/finally-seen-light/

Your other opinions are not supported by laws of war, international Geneva Conventions, our Constitution, Charter of Rights and Human Rights. 

As a military man, your leaders, like Romeo Dallaire have made this case very clearly both on the floor of the senate and in speeches across the country.
