This is very interesting and informative as a case study
In not too distant future we will be seeing this sort of thing here when the united states starts to fracture
I heard as much as 40% of Crimean soldiers immediately traded their Ukranian passports for Russian ones in the days immediately following the Russian deployment of troops (which btw were already present on Crimean soil)
Where would American soldiers go to? Mexico? It would have to be there, because I can't see the Canadian gov't accepting them... not with Prime Minister Harper in office. He may dislike Obama, but he marches lock step with those who give Obama his orders.
