My favourite was the North American alliance - apparently when it all goes pearshaped, oilwise, the US, Canada and Mexico will band together to form a superpower. Not so unlikely, but aparently, in the interests of fairness, each country will be policed by the police of another - Canada by the US police, Mexico by the Mounties, and the US by the Mexicans.
The US, allowing themselves to be policed by the Mexicans?
That, and the chemicals they put in aircraft fuel, to subdue the masses. Coz the masses are so subdued, right?
