On second thought, however, I retract my previous statement. The 1918-2018 period in the region has been so brutal that it compensates the population growth for the OP question purposes. The sum total for the Iran-Iraq Gulf War, Lebanese, Syrian, Yemeni and Libyan civil wars, Italian reconquest of Libya, recurring Kurdish insurgencies, successive Arab-Israeli wars, innumerable bloody repressions by essentially all the regional regimes at various times (with the Shah and the Baathist governments being particularly egregious, but Qaddhafi, the Saudi Monarchy, the Egyptian military and Republican Iran also contributing greatly), the various colonial conflicts and anti-colonial rebellions, the Turkish wars of "independence", the conflicts in the Arabian peninsula in the interwar period, the local front of WWII (albeit a secondary one), the American invasion of Iraq, and a few other "minor" conflicts and disturbances (Cyprus for ex.) probably created an average level of political violence per capita that outweighs the still very bloody preceding century even on a per capita basis.
