It is interesting to add, that the allies also dismissed the British non constitution and its archaic unrepresentative and undemocratic first pass the post system. It was the greatest service along with the Marshall Plan that the Allies could do for a war ravaged Germany. Now if they did the same for Iraq and Afghanistan maybe the Middle East wouldn’t be in such a mess.
