Afghanistan, Iraq, the Balkans, Northern Africa, all of these regions and states have one thing in common: Western military interventions. Whether we're talking about the so called "the war on terror", or NATO actions, European military has a major role.

When is it alright, or necesarry, for us to take place in a military intervention?

Is Europe benefiting from the alliance with USA, or we still owe them for the WW II?
