Democracy by its definition has voting. A dictatorship can't be democratic.
As for war being the worst thing in the world, think about North Korea. How many civilians are starving to death because of economic sanctions. Lets be clear, under a dictatorship people are going to be killed. The Government will do it, the world will impose sanctions strangling the economy and hence the lower and middle classes.
Killing Kim Jong Il would be an act of mercy. North Korea is out of control and i'd absolutely support taking him out. I absolutely support international intervention and even though i'm an Australian, i'm proud of the US for stepping up to the plate when the useless Europeans refuse to do so. And yes, i'm also proud of the Australian soldiers in my family that served in Iraq, and I believe their cause was noble. I did in 2003 and I still do.
The number's were off the top of my head, and weren't perfect. Here's from Wikipedia:
By the US
US forces killed an estimated 90,000 South Vietnamese civilians due to their extensive use of fire power (artilery, bombings, small weapons). Another 1,500 were killed in various massacres. [16] Again, these are deaths caused by US Forces apart from combat deaths inflicted on North Vietnames forces.
By North Vietnam
An estimated 95,000 civilians died in the communist re-education camps, another 500,000 were involved in forced labor projects, which killed 48,000 civilians. Another 100,000 were executed. Finally, 400,000 boat people died while trying to flee Vietnam. This is 643,000 killed during the consolidation of communist rule.[17] This consolidation ended around 1984, although boat people deaths occurred through 1988. A similar high death toll occurred in North Vietnam during 1950s when the Communists consolidated power in that geographic region.
You also have to calculate the massacres pre and post war, which are in the millions.
