This is an outrageously euro/america-centric world view. A war isn't "minor" if you're murdered in it. The Second Congo War alone killed nearly 5 million, the Soviet Afghan War killed nearly 3 million, Bangladesh nearly 3 million, Ethiopia/Eritrea 2 million, who knows how many in Ukraine and Gaza. While no one war approaches the loss of life in WW2, these are far from minor skirmishes.

I struggle to consider Syria, Myanmar, Somalia, or Sudan minor conflicts. Likewise, what is the measure of stability here considering the rate of civil wars and country creation?
