Ethics of pilots fighting for the sides in WWII

[Oktoberfest]

Well, as John Lennon said, Imagine...

I think I'm happy to live in a peaceful Europe, with friends from Germany, Belgium, Netherlands, Croatia, Poland, England, Ireland, etc... all joining in a virtual sky to fight with and against, but where the end of the fight is usually join the girlfriend and not sleeping on a muddy field, half frozen with shells incoming...

What was good in WW2 ? Nations grew adult and started talking together. Peace was paid at the cost of millions of lives, and just because those people allowed me to have friends in Europe and live in peace, I have the deepest respect for them.
