I don't why ? You are saying highly explosive whereas it is written as "The explosive device was made up of alarm clocks, fireworks, petrol tanks, propane tanks and fertiliser. " on BBC. For reference please see the following link, http://news.bbc.co.uk/2/hi/americas/8660419.stm
No one can deny Pakistan has lots of problems, but why you people portrays to the world that, Pakistan is base or origin of every problem across world.
I personally feel very ashamed on this act. What he got from this, or what he may have gotten even if he had fled from them successfully. I just pray to Allah, please drive us towards the right path.
At the end I won't hesitate in saying we should hand over the Pakistan to Americans. I think they can better administer the country. Perhaps may be good for the prosperity of peoples :)
