Were political cartoons part of the causes of U.S. support for World War I and for World War II?

Political cartoons were a factor in swaying us to join World War I, to support the Allies in World War II before the attack at Pearl Harbor, and to support our war effort once we entered both wars.

Political cartoons were a factor in swaying us to join World War I, to support the Allies in World War II before the attack at Pearl Harbor, and to support our war effort once we entered both wars.


The media had a big impact on American public opinion. Newspapers were a major source of information for many people in the 1920s and in the 1930s. Many political cartoons showed the Germans in a negative light. The cartoons showed how German submarines were killing innocent American people. They showed what the world would be like if the Axis Powers defeated Great Britain prior to 1941.


During both wars, political cartoons and posters encouraged Americans to support the war. People were encouraged to buy Liberty Bonds. They were encouraged to be careful of what they said because German spies could possibly be in our country. The phrase “Loose lips sink ships” became popular. People were also encouraged to conserve food and to grow their own vegetables.


The use of political cartoons and posters helped sway American public opinion to support our decision to join the Allies in World War I, to support Great Britain before the attack at Pearl Harbor, and to support our war effort in both World War I and in World War II.

In chapter one of The Great Gatsby, what advice does Nick's father give him? How does this make him a good person to tell this story?

Nick says that his father advised him that, before "criticizing anyone," he "remember that all the people in this world haven't had the same advantages" as Nick.  As a result, Nick claims that he is "inclined to reserve all judgments," presenting himself to the reader as a fair and dispassionate arbiter of character, and thus, a reliable narrator.   The problem is that Nick immediately reveals himself as anything but reliable, as he then launches...

How did the United States become an imperial power?

"Imperial power" is a bit of a vague label. It tends to mean several things at once, so let's unpack it. In the sense of "this country was built on conquest by force," the "imperial power" part of America actually predates the United States proper. The territories that would become the United States were imperial colonies, established by the great European empires of the 17th and 18th centuries. Much of the US Constitution and American governance generally goes back to England, history's largest and most successful imperial power, but vital aspects of American culture come from other imperial powers, such as France and Spain. Much of American culture comes from sources other than the old empires, but they were key influences on what the United States became. In the sense of "this country treats conquest by force as a fundamental component of its culture, economy and politics," the United States has always been an imperial power. Even earl...
