Why did The US abandoned neutrality and entered World War 1 on the other side of the allies?

The U.S. abandoned its neutrality and entered World War I largely due to unrestricted submarine warfare by Germany, which threatened American lives and commercial interests. The sinking of ships like the Lusitania, coupled with the interception of the Zimmerman Telegram—where Germany proposed a military alliance with Mexico against the U.S.— galvanized public opinion for war. Additionally, economic ties and loans to the Allies created a vested interest in their victory. Ultimately, these factors compelled the U.S. to join the conflict on the side of the Allies in April 1917.
