In my attempt to understand JFK better, i cruised on a series of books on various world events during that time, before and after, numerous conspiracy theories, his business approach and push for disarmament.
The biggest takeaway : It is much harder fighting for peace and disturbingly easy facilitating wars.
He practiced non-intervention. He wanted to pull out of Vietnam, establish peace with Castro, leave Laos, end the Cold War. He stood his grounds even when CIA went behind his back numerous times.
Should he have lived, cold war might have ended sooner. capitalist and socialist may have learnt to work together, even within America. The Islamic militant groups who rose a few years after he died, to oppose US and Soviet intervention, may not have existed. The Jihads - the far right of the Islamic Militants - likely would have faded.
Fighting for peace is definitely way harder. But its the only thing that matters.
