Many of those trips to war were at the call of the UN to help others gain safety and freedom. Not at all sure about your numbers you quoted, some seem OK and others are way out of line for Iraq operations. Especially those numbers of Iraqi killed. Those killed were not because of the UN forces in there at all. The Iraqi folks were split between the Sunni and Shiite types busy killing each other. Not because of any US, or English, or other nations sharing the job of keeping the people safe and helping them to get food, medical, housing, in spite of the often created war times from themselves against themselves.
None of us should have left when we did if we wanted peace to evenutually take hold down there. Look what the governments did for Europe after WWII. We kept plenty of troops in place and helped hold the peace until the new governments had time to take hold and maintain themselves. Peace in Europe has held for many more years than any time prior. Wars in Europe for centuries, one after another, till after WWII. Peace held as the countries like US, England, and other countries held troops in Europe and especially in Berlin area where Russia had threatened to take over. Our combined military's held the line and slowly peace kind of soaked in to the mind set. That is what should have happened to the Iraq situation. Not just hit and run, the old way of pretending to win but losing in the long term.
We still keep troops in Korea to help hold the truce line. We kept troops in Japan for many years after WWII. Peace is hard to win and ending hostilities is not peace itself. Peace only comes after years of being occupied and the ideas of peace can be taught to those who have traditionally carried hate for each other. A spell of peace helps people to learn they can live together.

That site also gives 'numbers' with reference to Iraq. And sure, there might be a few too many or maybe not even all that should be there, but when all is said and done, they're dead or injured and it's neither here nor there whether they were Sunni or Shiite. The point is that if the US wasn't there, had stayed home, this discussion wouldn't even be going on.
And seriously, if you still think this was all about 'spreading democracy' then you have swallowed the Kool-ade. If Saddam Hussein hadn't been trying to bypass the dollar and sell his oil, accepting euros instead, I seriously doubt if America would have fomented the lie of WMD. Same with Gaddafi. If he hadn't been planning on selling his oil and bypassing the American dollar and accepting gold instead, America wouldn't have bothered. This is strictly about control and power of position. Hit and run isn't exactly what I would call ten years in Iraq.
America brought down the Soviet Union via oil price manipulation, was happy to 'aid' Russia when they were facing food lines and empty shelves but as Russia became stronger and began to stand on their own two feet and opt for their own sovereignty, the animosity towards that nation resurfaced and has now bubbled over again. And in part the fact that Russia is moving away from the use of the American dollar has only added fuel to the fire. If Russia had bowed to their 'saviour', none of this would be going on, NATO would be surrounding them and America would be continuing to rake in the power and finances that comes from being the holder of the reserve currency. By means of that status and no gold standard, America can print money ad nauseum and to the detriment of the finances of your country.
According to
http://www.tradingeconomics.com/russia/government-debt-to-gdp, Russia's debt to GDP in 2014 was 13.41.
According to
http://www.tradingeconomics.com/united-states/government-debt-to-gdp America's debt to GDP in 2014 was 101.53
Russia has maintained a gold standard despite everything, they bought 55 tonnes of gold last year and they are either beginning to or planning to sell their oil for either rubbles or yuan. Their overall financial picture is better than America's despite the USA having the worlds reserve currency. If America were to loose that status, it would seriously impinge on your ability to borrow (budget crisis anyone?), your ability to continue printing money, to maintain your standard of living, support an enormous military......
Interesting note here, came across this article:

that is saying the Russia is doing not so bad right now economically and it has a short commentary by your own economist Dr. Paul Craig Roberts.
