Soviet Union, the USA and the UK won WWII. France was a witness

I've just learned that François Sevez, a Major General in the French Army,  signed the “Act of Military Surrender,” as witness. France was not among the winners of WWII as the following documents show -GERMANS SIGN UNCONDITIONAL SURRENDER - World War II Day by Day (ww2days.com) Essentially, this means that there was no winner except the Soviet Union in continental Europe. The best among European countries was a witness, then victims like Austria (where Hitler was born), and then losers and war criminals such as Germany and Italy.
