War & Peace Presidents

I always thought it kind of stunk that Obama got the Nobel Peace Prize simply by virtue of not being George Bush - I'm not George Bush either, and I don't see any international organisation giving me a check for 250,000 dollars!
The invasion of Libya this week got me thinking, though. Exactly what are the differences between the self-proclaimed War President (Bush 2), and the Nobel-proclaimed Peace President (Obama)? The physical black & white has already been mentioned in a previous post (here), but what about the timing of the invasion? Comparing dates of key events is made simple by the fact that both presidents were inaugarated on 20th January (2001 and 2009). The Invasion of Iraq began on 20th March 2003 - a war aimed at ousting a dictator in an oil-rich country. When did the Invasion of Libya begin (also a war aimed at ousting a dictator of an oil-rich country)? You guessed it - 20th March 2011 - exactly 790 days into each presidents' first term in office.
This overlapping of history doesn't fit perfectly for all major events - obviously if there had been a terrorist attack on or around 11th September 2009 we would have all noticed! - BUT we do find that on the 9th September 2009, Obama became the first US president to preside over a UN Security Council meeting. Okay, no major correlation there, I suppose. But HEY!!! What about the invasion of Afghanistan? That happened on the 7th October 2001, right? And Obama didn't invade anyone around that time did he? No. He received the Nobel Peace Prize! (two days later, on the 9th of October). So he didn't just get the Nobel Prize for not being George Bush - it was also to show that he was the Peace President because he did not invade an oil-rich nation on that day!
