Out of Nowhere

In the not-too-distant future, world peace, prosperity and democracy had reigned for twenty-six years, but is suddenly shattered by an unimaginable attack of ballistic missiles upon the United States by an unknown enemy from an unknown location. The President and major figures in the Government are killed in the strike. A small contingent of US military are all that remain to defend the Nation and the world against the missiles from out of nowhere. Would there be a second wave of attack upon the US, or against other nations? Who is the enemy? Where is the enemy? Why did they attack? The answers are startling.
