Granted, the French, Belgian, Portuguese and Italian former possessions are generally worse than British ones but they're still pretty terrible. If we look a bit closer to home I don't think the Irish are very happy about the "civilisation and stabilization" process we forced them to undergo. There's probably a lot of dead Tasmanian aborigines right now whose ghosts aren't very happy about what happened either.
Irish and British blood goes all the way back and would always have been shit regardless of the Empire having existed or not (unless the two countries fought together in the great war or something). Without any unifying factor like that, the two will always be antagonistic to one another.
Portugal, good god Portugal's Empire.
France, nuff said.
But for Britain? I can think on the top of my head other than splitting Pakistan/India and the mess that is the middle east, it did pretty well. Especially considering the amount of countries it influenced, just look at Canada, Australia, Hong Kong, New Zealand, Malaysia, Singapore, India, Kenya, Tanzania, Ghana, Sri Lanka, Jamaica, Namibia e.t.c.
Aborigines 'nuff said, it wasn't a "civilization" effort it was just colonization. Better it have been done by British than some other European power though. I don't get how people can focus so heavily on smaller things whilst brushing over bigger things, if you want to look at the ill of the British Empire look at shit like the opium wars. I'm glad the British Empire died the way it did, bankrupt from fighting Nazism and peacefully granting independence to its members.
