President Donald Trump announced that the United States will join several nations in celebrating Victory Day on May 8, seemingly unaware that World War II only ended in Europe during that month in 1945 — as America continued fighting Japan until August.

“Many of our allies and friends are celebrating May 8th as Victory Day, but we did more than any other Country, by far, in producing a victorious result in World War II,” Trump wrote Thursday night in a lengthy post on his Truth Social platform.

“I am hereby renaming May 8th as Victory Day for World War II and November 11th as Victory Day for World War I,” he continued.

Nazi Germany surrendered to the Allied forces on May 8, 1945, a little over a week after Adolf Hitler died by suicide inside his Berlin bunker. Russian forces had captured the German capital on May 2 after their former Soviet Union lost an estimated 24 million people to the war.

Victory Day is celebrated annually on May 8 by several former members of the Allied Powers, such as France, Poland and the United Kingdom (which calls it VE Day). Other nations, including Belarus and Russia, however, commemorate the end of hostilities from the Axis Powers on May 9.

Trump, who is reportedly eager to hold a 4-mile military parade on his birthday in June, argued Thursday in his post that the U.S. “never” publicly marks its wartime victories — and appeared to blame current or former leaders for this supposed lack of patriotism.

He wrote: “We won both Wars, nobody was close to us in terms of strength, bravery, or military brilliance, but we never celebrate anything. That’s because we don’t have leaders anymore that know how to do so! We are going to start celebrating our victories again!”

Frustrated social media users have since pointed out that Nov. 11 would apparently no longer honor all U.S. veterans under this newly announced plan, however, as has been the case for 70 years now, and only be dedicated to those who served during World War I.

Former President Woodrow Wilson declared Nov. 11 Armistice Day in 1919 to celebrate the end of WWI after the signing of the Treaty of Versailles. The date was officially replaced by Veterans Day in 1954 under former President Dwight Eisenhower.

Trump himself has never served and reportedly avoided the Vietnam War draft with a diagnosis of bone spurs in his foot. The daughter of the doctor who provided the diagnosis later said he had made that determination as a favor to his landlord — Trump’s father, Fred.

The Victory Day announcement has sparked outrage and confusion on X, formerly Twitter.

“We won World War II on August 15, 1945 when the Japanese surrendered. Trump is a complete moron,” wrote former MSNBC host Keith Olbermann, with another user asking: “Why is Trump … erasing all post WWII veterans and their accomplishments.”
