If someone from ISIS killed my leader I'd be all broken up. I probably wouldn't be able to carry on and might end up in a dismal tail spin of quiet despair.
The former leader of the West and current Commander-in-Chief of the United States Armed Forces lives on the pennies he earned as a community organizer in the most deadly and violent city in America and currently lives in the only house still standing on his block in one of America's other poorest and most violent cities. One of his predecessors moved out of that house claiming to be flat broke and stole much of the remaining old furniture on her way to the poorhouse. Like his predecessors, he's not afraid of anybody and unlike many before him, he doesn't believe in the right of self-defense.
