In its post-medieval history, Europe has experienced a major war once every one to two decades, with the exception of the 71 years since the end of WWII, which has experienced no major war in Europe.
That's not an organic phenomenon; it is the direct result of American-influence and building a common concept of what it means to be "European." Both are now under intense scrutiny, ranging from violent reactionary skepticism in its worst case and questioning the coherence of European identity in its best.
If Europe fails, which it probably will, as I am a firm believer in the universal law of entropy, then I suspect that war is in its future. Europeans have never really liked one another. The last 70 years have been an illusion, but one that was worth perpetuating. It was a well-intentioned idealism that just happened to align with pragmatism, often a rare combination, but it most likely won't last another decade or two.
