the thing is ...history is not like a hot/cold water sytrem.

we didn't get the electoral reform act of 1870 and the NHS started the next day.
Libyans can't expect that you get rid of Gadaffi and then peace and harmony will break out. its unrealistic.
that's why people want to move here. its a done deal. our parents starved in the 1930's, and fought and saw their folks killed in WW2 to enjoy the life and affluence many of us enjoy.

you can't blame people for not wanting their families to be caught up in all the shit that's going on in their societies,

ultimately though, their countries have to fight and evolve their way out of the shit themselves. killing kids in Warrington, like the IRA did, or Manchester like this nutcase/freedom fighter did is no part of the solution.
