Abu Hamza and his kind have done nothing but preach hatred and harm against the UK and peoples since they so called adopted [sic] our country
Not true. After coming to the UK in 1979 he was on the same side as the British government in Bosnia and Afghanistan, and the British government had no issues with him killing people or preaching hate against them in those two countries.
Like Saddam Hussein before him, Abu Hamza has proved to have been a friend and ally to the US and the UK who eventually turned out to be rather difficult to control.
Of course none of this should have come as a surprise to anyone as the warning signs were clearly visible for all to see. But the West has a long history of supporting extremely nasty pieces of work based on the shortsighted policy of achieving immediate aims which serve greedy self-interests. Something which of course it still does to this day.
I have always associated the ridiculous greed motivated risks which the West takes with some form of serious gambling addiction - the likely consequences are simply ignored. But then we celebrate and richly reward those who we are told "take risks".......even after it all very predictably causes a devastating global banking crises, so I guess nothing will change for a very long time.
