And I wish people would stop focusing on the UK as some great evil in CoE. The governments of EVERY nation on the planet were complicit--probably the only difference was how they were going to fill their quota.
I would gladly spread blame around if any country besides the U.K. had been given any significant screentime.
Besides, in speculative fiction, whenever there's a crisis, it seems like the U.K. is always the first country to descend into chaos or totalitarianism. (SEE Children of Men, V for Vendetta,
I also have a hard time believing every government in the world would be cooperating with 456's demands. I can't imagine these sorts of alien demands going over well in an Islamic theocracy like Iran. Then you have countries like Afghanistan where the government is so disorganized & incompetant that it can't even find its own ass with both hands. Countries like this couldn't cooperate even if they'd wanted to.
