Agreed, but the results are incredible on the scale of human history. Under Pax Americana, look at the amazing spread of liberty and democracy, and of prosperity, to people worldwide.

No, it's not, in the usual scientific sense of proof rather than some absolutist one; you show the expected incidence of the inhibitory effect did not exist, and then show that the actual value (either by surveying the whole universe of concern or a random subset) is below that expected value to a degree that makes it improbable that it occurs by chance, while controling for other known sources of variability.
> but can you cite and exception?
Sure, if you use a definition of Democracy that isn't so narrow that the expected number of wars if democracies on both sides isn't far less than one, you will also find lots of actual wars between Democracies. Even if you ignore wars where the only pair of democracies are a separatist group and the unit they are separating from (e.g., the American Revolution), there are plenty (War of 1812, for instance, or more recently some parts of the Yugoslav Wars.)

> have non-democracies ever achieved anything like the EU or NATO?
Yes, non-democracies have created both continent-spanning multi-national supergovernments like the EU and wide regional military alliances like NATO.
In fact, they did both long before democracies did.
