It is easy to cherry-pick data and arrive at bogus conclusions, but even the data you show indicate a big increase in war after a flat lower number for the last two decades. The recent increase in violence needed to include the terrorist attacks of Islamist fundamentalists, from Al Qaeda, ISIS/Daesh, Boko Harum, Hamas, and the Palestinian Intifadas, as well as the Sunni/Shia wars in Iraq, Syria, and Yemen. And we can’t forget the Taliban in Afghanistan or the Russians in the Ukraine. Meanwhile the signs of danger from Nuclear North Korea and Nuclear Iran portend war at a far larger scale than seen since WWII. Your your article could have been written in 1930 — we are leaving the lull before the storm, a lull that has been coming to an end which you have mistaken for sunny weather that will last.
