I don't oppose all wars. What I am opposed to is a dumb war. What I am opposed to is a rash war.
Barack Obama

We're not going to baby sit a civil war.
Barack Obama

There are patriots who opposed the war in Iraq and there are patriots who supported the war in Iraq. We are one people, all of us pledging allegiance to the stars and stripes, all of us defending the United States of America.

The most successful war seldom pays for its losses.

I have seen enough of one war never to wish to see another.

War is an instrument entirely inefficient toward redressing wrong; and multiplies, instead of indemnifying losses.

I abhor war and view it as the greatest scourge of mankind.
Thomas Jefferson

War grows out of the desire of the individual to gain advantage at the expense of his fellow man.
