"The creation of the EU may or may not have helped to bring peace in the beginning"
May or may not? Care to point out the last war between EU members?

Just because the EU happened to exist during a period of peace, does not mean it is the reason for it. There was a little thing called World War 2 that may also have played a part.
If you take out the 'first world' bit, then yes, there's been plenty of war between democracies, including World War I: http://users.erols.com/mwhite28/demowar.htm
I think my point stands, it's pretty rare for democracies to go to war. If you take the example of WW1, I doubt many people would consider Germany to have been a democracy in our modern understanding of the word.
Anyway where's your evidence that the EU somehow prevents war?
There's nothing to stop the EU going to war with someone else (when they get a military) for starters.
