"The first casualty when war comes is truth." Hiram W Johnson. This quote is also sometimes attributed to the Greek dramatist Aeschylus.
It’s not easy to get Americans to support war. In 1917, President Woodrow Wilson appointed journalist George Creel as Chairman of the new Committee for Public Information. In an article for The American Experience, Nicholas Cull wrote, “For two years, he rallied the American public to the cause of war and sold the globe a vision of America and President Wilson’s plans for a world order. He was a controversial figure in wartime Washington, but his efforts changed the ideological landscape at home and abroad, and many of the methods and approaches he pioneered became a standard part of U.S. statecraft.”
Near the beginning of the 21st century, George W. Bush and his team made the case for war in Iraq based primarily on intelligence reports that the regime in Iraq was hiding weapons of mass destruction. The war was undertaken and Saddam Hussein was captured. However, the evidence of WMDs was not as strong as the pre-war intelligence indicated.
