Sorry Leo - my first reaction was a little over the top and came over as a personal attack, it wasn't meant that way.
However, you say that the British empire (and others) established democracy and infrastructure throughout the World - even if this were the case it took sovereignty away from others through brutal means. Does this mean I am justified in invading another country because it raises their standard of living ? Most of the cases of brutality which I quoted came from the 20th Century - some after the war, and were not representative of their age. It is impossible to calculate what the World would be like now had colonialism never happened. Maybe the Sioux would still be chasing the buffalo, maybe the aborigines and Maoris would still have their land, maybe Africas`borders would now be more tribally and organically based than the colonial ones we left them with. Maybe Hindu and Moslem would be living together in peace in India. Maybe the World of Islam would not have become as militant and inflamed as it has. We do not know because history developed in a different way.
The legacy of empire is, however all around us, to an extent it defines how many older British people feel about Britain - about the EU, about the monarchy, and about the rest of the British Isles. This legacy also transforms itself 'naturally' into Britains' assumption of the role of junior world policeman behind America. British forces have been involved in active service overseas, somewhere, every year since the conclusion of World War 2 under the guise of peace keeping - and this appears somehow 'normal' because of our history.
I do not want to go back - but, at the same time, I do not believe that movement through time necessarily equates to progress. I would support birth control programmes by the way. I also want a new definition of democracy, because I am not happy with yours. For some reason we are told that capitalism must grow and develop (but not democracy ?) - we are told that we have democracy - because the best way of stopping somebody from fighting for something is to convince them that they have it already. In the West you have what is called representative democracy ie. all ideas come from political parties (In the UK just 1% of the population) and the population are invited every 5 years to vote yay or nay. Do you call this democracy ? I favour a direct democracy where the organ of decision making has moved to the base of the pyramid and the role of the state has become purely administrative - I also believe in the establishment of democracy in every area of life, including within economics (which is why I favour the cooperative as the future model of production) - does all this imply that I am looking backwards ?
