The Third Wars

When talking about World War 3, most people usually imagine a nuclear apocalypse or nuclear war. A war that will completely exterminate human civilization, leaving only radiation and the ruins of destroyed cities on Earth. What if, however, in a parallel universe in which the Soviet Union survives after 1991, nuclear weapons don't exist, and World War 3 is a war with the most advanced weapons from both NATO and the Soviet Union? A place where M1A1 Abrams and T-14 Armata collide and tremble the ground, where F-35 and Su-57 terrorize the skies. How would a war like this look like? And what if, even military weapons that were thought to come out of science fiction, such as laser guns, jetpacks, and lightsabers are used in The Third Human Global Conflict? Although everything would appear to be incredibly epic, it all began with a simple terrorist attack on New York City, which would slowly drive humans toward total annihilation. ---------------NOTE--------------- In this novel, I will call NATO as The Alliances, because the Alliances is a league where all anti-communist nations come together rather than just "North Atlantic nations". Also, everything in the Novel is entirely fictional, meaning that the whole world history in this novel is all made up and based on the real world, so don't accuse me of historical inaccuracies.
