It will most likely won't start, because the fact that not enough russian and japanese people didn't sign the papers to end WW2, So we are still in WW2.

ME WHEN I REALISED GTA 6 WILL NEVER COME OUT; WHEN I GOT 1000 VIEWS ON IMGFLIP BUT NOT A SINGLE UPVOTE; WHEN I REALISED WW3 WILL START IF UKRAINE LOSES THE WAR
