As I said before, I relly think that you can't have one answer on this kind of topic. Each person has his "reality" and evidence that the country he's talking about is the one that made the worst decisions. I think that every country on this planet, at least once during its history, made a bad mistake that led to a useless and unnecessary war.
I don't think there are worse countries than other, even though some of them might spring to mind easier than others , as France and the USA...
