The sinking of ships carrying Americans
In World War II (as distinct from World War I), the long-planned but often-delayed strike on Germany that finally opened a genuine Second (and Western) Front arrived on June the 6th of 1944. Often referred to as "D-Day", this invasion took place in the Normandy region of France and was successful in leading to the eventual overthrow of Nazi Germany.
The final action taken by Germany that prompted President Woodrow Wilson to ask Congress for a declaration of war was the resumption of unrestricted submarine warfare in early 1917. This aggressive military strategy threatened American ships and lives, leading to the sinking of several vessels, including the Lusitania in 1915 and later incidents that endangered American citizens. Additionally, the interception of the Zimmermann Telegram, in which Germany proposed a military alliance with Mexico against the United States, further inflamed public opinion and galvanized support for entering the war. These factors combined led Wilson to advocate for U.S. involvement on the side of the Allies.
Three things that led the Congress and President Roosevelt to declare war on Germany were:Japan attacked the United States. This was the impetus that finally allowed the president and congress to declare war on both Germany and Japan.Britain was desperate for help. Winston Churchill had sent numerous requests for the assistance of the US.Hitler's invasion and murders in other countries moved the US to stop Hitler in his tracks.

The Japanese attack on Pearl Harbour on 7th December 1941 followed by the German declaration of war on the US on 11th December.
President Woodrow Wilson asked for a declaration of war against Germany after the sinking of the Lusitania in 1915 and the escalation of unrestricted submarine warfare by Germany. However, the final catalyst was the interception of the Zimmermann Telegram in early 1917, in which Germany proposed a military alliance with Mexico against the United States. This act, combined with ongoing attacks on American ships and a desire to protect U.S. interests, led Wilson to seek congressional approval for war on April 2, 1917.
President Wilson asked for a declaration of war against Germany primarily in response to unrestricted submarine warfare, particularly after the sinking of the British ocean liner RMS Lusitania in 1915, which resulted in the deaths of American passengers. However, the final catalyst was the revelation of the Zimmermann Telegram in early 1917, in which Germany proposed a military alliance with Mexico against the United States. These provocations, combined with Germany's continued aggression, led Wilson to seek a formal declaration of war on April 2, 1917.
President Wilson asked for a declaration of war against Germany primarily due to the resumption of unrestricted submarine warfare by the German Navy, which posed a direct threat to American ships and lives. Additionally, the interception of the Zimmerman Telegram, in which Germany proposed a military alliance with Mexico against the United States, further inflamed public opinion and solidified the call for action. These events collectively pushed Wilson to abandon his earlier stance of neutrality and seek congressional approval for war.
Germany's declaration of unlimited submarine warfare
The Zimmerman Letter
the Declaration of Independence was finally published, on the Fourth of July, 1776
The event that finally compelled the American colonies to recognize their independence and enter the war against Britain was the Declaration of Independence, adopted on July 4, 1776. This pivotal document asserted the colonies' right to self-governance and formally broke ties with British rule. Following this declaration, the Revolutionary War intensified as the colonies united in their fight for freedom against British forces.
"The Government of the United States having violated in the most flagrant manner and in ever-increasing measure all rules of neutrality in favor of the adversaries of Germany and having continually been guilty of the most severe provocations toward Germany ever since the outbreak of the European war, provoked by the British declaration of war against Germany on September 3, 1939, has finally resorted to open military acts of aggression."

1) The British found a letter written by Germany that tried to get Mexico to declare war on the USA, and 2) Germany said they were going to resume unrestricted submarine warfare and sink any ships (civilian or military) sailing between the USA and England. These two actions finally provoked President Wilson to ask the Congress to declare War on Germany.
He or she would have to start by entering primaries and competing at caucuses and then finally win the nomination of the party at its convention.
The United States' participation in World War I was primarily triggered by a combination of factors, including unrestricted submarine warfare by Germany, which resulted in the sinking of civilian ships like the Lusitania, and the interception of the Zimmermann Telegram, in which Germany proposed a military alliance with Mexico against the US. These events, alongside growing economic ties to the Allies and a desire to protect American interests, ultimately swayed public opinion and led President Woodrow Wilson to ask Congress for a declaration of war in April 1917.
Great Britain and France declared war on Germany on September 3, 1939, in response to Germany's invasion of Poland on September 1, 1939. Both countries had pledged to support Poland in the event of aggression, viewing Germany's actions as a violation of international agreements and a threat to European stability. The invasion marked a significant escalation of Adolf Hitler's expansionist policies, prompting the Allies to take a stand against further Nazi aggression. Their declaration of war aimed to protect Poland and contain the growing threat posed by Germany.
