I thought you took on board previous questions from other threads, obviously not.The European Union did not stop the fighting, by that time the Russian Federation had taken South Ossetia and the other region, there was nothing to stop and still, those regions remain under Russian control. The EU did jack all.
Chechen War
Kosovo War
Bosnian War
..more here.
On the final point, we are not talking about other threads. In this discussion you said "have there been any European wars?" when I answered this you then changed the question to "did these wars rage through europe?"
Btw I said wars in the last 5-10 years, and the Russian war on the bottom was part of the USSR when it split.
And yes the French presidency of the EU helped reach agreements.
