I have just read an interesting book "A World Without Islam" by Graham E. Fuller on the tragedy of 9/11.
Inter-alia he stated: ...... "the attack was indeed shocking, outrageous, and a tragedy for the innocent
civilians that died.  But it should not have been a surprise.  Given US policies in the Middle East and
the rising Muslim anger over such a long period of time over so many issues, it was inevitable that sooner
or later some Muslims would strike back.  The US courts further such attacks as long as it maintains
the same policies of global dominance and political and military intervention. As terrible as the events
were, hopefully they may serve as a wake-up call to Washington to the seriousness of the situation
and the need for reconsideration.
Most Muslims painfully acknowledge that their own societies are riddled with deep problems.
My own view is that to right a wrong one should not commit another wrong. Might is not always Right.
This is a common, almost universal, human predicament.
