Firstly. I didn't say Constitutional Democracy, I said Country, and I meant it. Great Britain, and all the other countries that were originally part of her Empire and remain part of the British commonwealth are older. France, Spain, Portugal, Belgium, Hungary, Romania, Holland, Switzerland, Italy, Greece, Germany, Austria, Turkey, Ukraine, Moldova, Kazakhstan, Turkmenistan, Albania, Estonia, Bulgaria, Lithuania, Latvia et al, are all older, much older; and I haven't even started mentioning South and Central America ... These countries have all been through periods of dictatorship (some in the form of monarchies with absolute power) and lawless, immoral leaders. Its one of the reasons why monarchies in some of those countries have been overturned in revolutions, sometimes quiet, sometimes bloody. America is the NKOTB when it comes to this kind of behaviour from leaders.
Secondly, lawless, out-of-control leaders are not exclusive to Constitutional Democracies, and you don't have to be one for you people to experience what its like to have one.
