Current situation of Omar Kahdr, the Government at fault?

We have all heard of Omar Kahdr, and his detainment at Guantanamo Bay since he was 15. He is now 21 years of age and has still not been released or tried. We are now on the second Canadian government (the liberals in his first years of detainment, now the conservatives) that has not guaranteed or furthered agreements with the U.S. for Omar’s release. As the article points out, our PM states we have “no real alternatives”. At the same time the PM (Harper) condemns poor treatment and torture in other countries, like china, but does nothing for one of our own. Even if he is a war criminal he is a Canadian and that’s got to count for something. Omar has undergone nothing less but standard U.S. torture, including but not exclusively sleep deprivation, a horrible practice where the inmate is kept awake for unbearable amounts of time at once to “soften” them up for integration. A Fact that make this negligence on behalf of the Canadian government even worse is that we are alone in our abandon of our fellow citizen, I quote from the article Professor of law Amir Attaran ” Without exception, every other leader of a Western country has got their citizens out of Guantanamo”. Many other Canadians form academia, law related and not, have state their dismay and concern on the matter. Attaran even goes as far as saying that officials that were aware of the torture should be prosecuted under Canadian law for “aiding and abetting torture”.

Why has Canada and its officials remained so silent on the matter? Are we nothing but puppets in the hands of the United states?
