I don't think I can say why it is important to engage better than Charles Krauthammer, so I'll just put his words here.
"While science, medicine, art, poetry, architecture, chess, space, sports, number theory and all things hard and beautiful promise purity, elegance and sometimes even transcendence, they are fundamentally subordinate. In the end, they must bow to the sovereignty of politics.
Politics, the crooked timber of our communal lives, dominates everything because, in the end, everything – high and low and, most especially, high – lives or dies by politics. You can have the most advanced and efflorescent of cultures. Get your politics wrong, however, and everything stands to be swept away. This is not ancient history. This is Germany 1933… Politics is the moat, the walls, beyond which lie the barbarians. Fail to keep them at bay, and everything burns."
