Chandra - I am not a historian, I am a lawyer, but I also studied International Relations at the London School of Economics and I also have a Masters in Politics.
There are many ways to interpret history, but once you look at all the evidence available there is usually an undeniable trend of some sort, in this case the fact that Britain, both past and present has mistreated certain countries and communities.
How do you as a historian draw "conclusions" ?? Do you not look at historical evidence ?? Of course the "evidence" can change (i.e. more is added to it or some of it becomes unreliable, etc as in a legal case), but is there any one who can point to Britain's colonial past and say, "no" it didn't exist or that it was glorious ?
Some have tried to argue that the "holocaust", did not take place, but none of us with any intelligence take them seriously.
The point is, there are entire communities and countries who are alleniated and have suffered at the hands of British and American foreign policy.
No matter how nice we think it is sitting in a pretty rose garden of a beautiful Englsh country home and sipping Earl Grey tea all afternoon, how does it address the real concerns of those communities ?
