What a lot of people don't get, including the Americans, is that having an election is not the only requirement to qualify as a democracy.
"According to political scientist Larry Diamond, democracy consists of four key elements: (a) A political system for choosing and replacing the government through free and fair elections; (b) The active participation of the people, as citizens, in politics and civic life; (c) Protection of the human rights of all citizens, and (d) A rule of law, in which the laws and procedures apply equally to all citizens"
So, even if we assume that the elections in Turkey are free and fair, which they aren't, they still fail c) and possibly even d).

At least you agree that the first Gulf war was justified. The 2nd Iraq war is different, but there are similarities. Imagine this situation: in 1939 Hitler does not invade Poland, but continues to arm himself, to try to build a nuclear bomb and exterminates the jews in Germany. Would the allies be justified in declaring war on Germany? If you think the answer is yes, which I do, then by the same logic the war on Iraq was justified.
