U.S.A Political propaganda phrases/ slogans

"Remember the Maine!" A slogan used when launching the Spanish-American War. The US population was whipped up into an hysterical frenzy when it was claimed by the sensationalist news media that the battleship USS Maine was sunk by the Spanish in Havana, Cuba, only to find out years later that a concentration of coal dust below decks in the air of a confined space with a spark was the likely cause.
