Way of a Rebel by Walter M. Miller Jr., Science Fiction, Fantasy (Hardcover) (ISBN-13: 9781463895242)

"In accordance with the provisions of the Twenty-Sixth Amendment, Congress today approved the Manlin Bill, declaring a state of total emergency for the nation. President Williston signed it immediately and tendered his resignation to the Congress and the people. The executive, legislative, and judiciary are now in the hands of the Department of Defense. Secretary Garson has issued two decrees, one reminding all citizens that they are no longer free to shirk their duties to the nation, the other calling upon the leaders of the Eurasian Soviet to cease air attacks on the American continent or suffer the consequences.

"In Secretary Garson's ultimatum to the enemy, he stated: 'Heretofore we have refrained from employing certain weapons of warfare in the vain hope that you would recognize the futility of further aggression and desist from it. You have not done so. You have persisted in your blood-thirsty folly, despite this nation's efforts to reach an agreement for armistice. Therefore I am forced to command you, in the Name of Almighty God, to surrender immediately or be destroyed. . . ."
