And, Biggus, as with all "first past the post" votes, those percentages could be the result of, say 50% of those eligible casting a vote - in no way representative of the whole population (so 25.0001% could decide the fate of a nation) - before anyone gets all het up, this is only illustrative of the vagaries of the voting system.
Just another thought on the military/defence aspect - who would be expected to pay the pensions for any "defecting" personnel?
