In my opinion a old man as him should not be hanged instead of that he should have been imprisoned for life long if he commited guilty.
I would rather like to say that it is not the fault of USA but of us who are just watching by sitting in our home and doing nothing. The powerful countrie such as CHINA, UK, INDIA and PAKISTAN could have given pressure on IRAQ and USA against this decision.
We do nothing we just say oh! it should not have beeen done and then we forget him after some days.
If it continues like this then that day is not far when the whole world will be captured by US. So, my dear friends wake up its the right time to against the wrong and win our victory.
