Political leaders, East and West, are separated by more than custom, tradition, or practice. The divide is cultural.
Put aside for the moment obvious things like power differentials or even notions of winning and losing. The Caliph of the Islamic State is obviously having a better year than any politician in the West if anyone keeps score these days. The Friday the 13th Paris pogrom and that sabotaged airliner full of Russian tourists clearly go into the win column for Caliph Baghdadi. Kinetic failure in the West is again manifest: no Intelligence, no warning, no defense, and no real coalition. Canada defected from the deployed anti-ISIS team just days before the recent Paris massacre.
