I said this in another thread:
The more I think about it, the more true it seems. Civilization doesn't really handle modernity well. Modernity involves 100+ countries, with no nation in a "winner take all" situation, a UN that is guided by multiple nations sharing a common interest (no matter how corrupt or ineffective it might often be), terrorists of no nationality with no leader, and the line between civilian and soldier blurred by guerilla warfare.
It just can't be done in this game.
