World War 3 (Idkdom)

World war 3 gained the second most deaths of any war, gaining over 191.5 million people killed. The reason for this was simple, China had been preparing an invasion of Taiwan for many years, and it was planned that on March 21 of 2029, China would invade Taiwan, which they did, and it caused World War 3. The U.S.A's President Promised that it would defend Taiwan if a invasion happened, and they stuck to their word by declaring war on China, Japan got involved as well on the side of U.S. and after much consideration, South Korea also decided to be in the war on the U.S side, which immediately led North Korea to join and side with China. For unknown reasons Russia decided to join, also invading the Baltic states, activating NATO. 
The Beginning of the China-Taiwan Invasion
China starts their invasion of Taiwan at 2:39 am EST, they couldn't get to mainland of Taiwan yet, as their was hundreds of U.S Battleships waiting for the moment of Chinese attack, 7 out of 24 of America's aircraft carriers were there, and all 15 of China's carriers were there. The battle lasted for many days, one of the most fierce battles in the war. China, because of the naval battle, wasn't able to go on Taiwanese land until March 26th, when they barely defeated the hundreds of U.S naval ships, for the U.S 5 carriers were sunk, 1 highly damaged, and 1 very light damage, while for China 6 were sunk, and 3 were highly damaged. China then managed to finally send their troops to the Taiwanese mainland, over 2.2 million Chinese troops were sent on Taiwan, on March 26. There was 1.7 million American soldiers, and 400,000 Taiwanese soldiers.
Russian Invasion of the Baltics
Despite China's warnings, Russia invaded the Baltics and joined the war, also activating NATO. The invasion took place on March 26, 4:26 PM EST. Russia had been preparing for this for over 10 years, with over 1.5 million Russians soldiers going into the Baltics, Lithuania, Estonia, and Latvia and fell in around 16 hours, because of NATO's failure to quickly respond, and the U.S being unable to bring soldiers from North America to Europe in such a quick time. The reason 1.7 million American soldiers were already in Taiwan is because the U.S was preparing for a Chinese invasion, before the war even started, while for NATO, no preparation was made, and it would take the U.S around a week to get all the soldiers and supplies into Europe, therefore they couldn't help Europe defend until April 2nd. After Russia invaded the Baltics, they decided to invade Poland on March 27th for strategical purposes (for any of y'all wondering why Russia isn't invading Ukraine, in this timeline Russia took Ukraine over in 2024). This time many French, German, Italian, Spanish, and British soldiers were waiting in Poland. Russia still managed to take a small part of Northern Poland, but that was basically it. Turkey, a NATO member, had neutral relations with Russia, so against NATO's will, Turkey left NATO on the 28th of March, and stayed out of the war.
Battle Of Taipei
China had much better technology then many countries thought, as it was predicted that the U.S would crush China, because of recent U.S technological developments, but China seemed to be a lot more powerful then the west thought as, it managed to invade many cities, and even get soldiers to Taipei, the capital of Taiwan, starting the famous "Battle Of Taipei." The battle started on March 29th, and it was extremely brutal and long, lasting until April 30th. This battle alone caused over 1 million soldier deaths, as constantly China and the U.S were send more and more soldiers to this city, for it would determine the faith of Taiwan. But at the end, just barely the U.S won the battle, it was said that only a couple thousand more deaths from the U.S, and they would've surrendered. It was fairly surprising among the public as China was doing very well in Taiwan, but the nation was in ruins, completely destroyed.
Russia Getting Pushed Back
It was April 2nd, when the American soldiers arrived in Europe, over 1.8 million of them. NATO already pushed back Russia from Poland, but they weren't able to get back the Baltics. When the U.S.A arrived that changed in just 10 days, Russia was out of the Baltics. NATO was planning to invade Ukraine as Russia owned it, on April 16th 2029. A Russian spy managed to leak some of that info to the Russian government, Russia would send 1.1 million more troops to Ukraine, and they would go on complete defensive mode. NATO then attempted to invade Ukraine for around 9 days straight (April 16 2029 - April 25th 2029), but completely failed as Russia was prepared. They eventually stopped trying, and gave up on the Ukraine Invasion plan.
Stalemate
From May 1st 2029 to July 28th 2030, very little to no change across the borders was made. There were a few battles and bombings, but for the most part they were fairly small. Both sides had drained their resources highly so they just rested for a while, even North Korea and South Korea, even though they technically declared war on each other, they basically did nothing for the entirity war. That was until July 29th of 2030.
North Korea Attacks South Korea
On the 29th of July, in 2030, North Korea introduced mass bombings of Seoul, and a 2.1 million soldier invasion of South Korea. Surprisingly in just 6 days, North Korea took over Seoul, and around half of South Korea. On August 5th, Japanese and American soldiers quickly got to South Korea, and fought North Korean soldiers pushing them back, and even taking a small part of North Korea. As China saw that America was mainly focused in North Korea, it decided to further break the stalemate, and invade Taiwan once again. There was still around 2 American/Taiwanese million soldiers in Taiwan, making China's Invasion a failure once again, the U.S even managing to push out all Chinese troops out of Taiwan on October 16th 2030.
Argentina Joins The War
China promised Argentina mass amounts of money and military equipment after the war if they joined. Argentina agreed and joined the war on October 17th 2030, they didn't really do much but they did invade the Falklands on October 21st 2030. That's really all Argentina did as they weren't a very strong countries compared to others.
Russia Starts Losing Land
Russia's economy was now very weakened and so was it's military, because of the war it was a shell of it's former self, and NATO realized this so they decided to make a 2nd Ukraine Invasion plan, with over 1.6 million troops, which would start on October 27th 2030. It took only a bit over a month for NATO to take over Ukraine, on January 16th 2031. On January 19th 2031, NATO started invading Russia they managed to get a small part of Russian land.
Nuclear Weapons Are Used
Russia and China realized that they will lose this war, as China got completely kicked out of Taiwan and Russia now losing some it's land from the mainland to NATO, the leaders of Russia, China, and North Korea met on January 22nd to discuss what they would do after their recent loses that could lead them to lose the entire war. The meeting was held for 4 hours, and after a tough discussion they agreed that they will use nuclear weapons against the west starting on January 23, 2031. North Korea nuked Seoul in South Korea, Russia nuked London in the UK, and China nuked Tokyo in Japan, and New York in The United States. The nuclear weapons were used at the same time, and the west was speechless. The west knew that if they used nuclear weapons back, a nuclear war would emerge, which would cause the end of the world, so on January 23, 8:49 PM EST, the west surrendered saying they will agree to all terms that Russia, China and North Korea wanted.
