"So our population in signifcant majority support the president and his military actions, our congress who represent the American population support the president and his actions"

-- in matters of war alone, the same thing happened in 1964 (bombing of North Vietnam following Gulf of Tonkin), 1898 (Spanish-American War, "remember the Maine!", and the invasion of Cuba), and 1848 (invasion of Mexico in the Mexican-American War)
-- in domestic matters, you had popular and Congressional support for prohibition, denying women the right to vote, Jim Crow laws & slavery
-- conclusion: at certain moments in history, the will of the people and the will of Congress does not always coincide with our nation's highest principles, as expressed in the Constitution, the Declaration of Independence, and the Bill of Rights.

BTW, Lincoln also said this, about another moment in U.S. history: "Our progress in degeneracy appears to me to be pretty rapid. As a nation we began by declaring that 'all men are created equal.' When the Know-Nothings get control, it will read 'all men are created equal, except Negroes and foreigners and Catholics.' When it comes to this, I shall prefer emigrating to some country where they make no pretense of loving liberty -- to Russia, for instance, where despotism can be taken pure, and without the base alloy hypocrisy."
