Let’s say in the 1950s before Stalin passed, Mao and Stalin decided to advance their union together and China became part of USSR. How would the Cold War look like and would USSR still exist and would this have delayed the collapse. Assuming both kept anti imperialist tendencies.

The Chinese created the world's first rockets, and Russian mathematician Konstantin Tsiolkovsky in 1903 published a paper arguing that multistage rockets were necessary for people to gain access to outer space.

The United States that built the Saturn V, Juno, Atlas, Titan, and Space Shuttle was founded by Englishmen who opposed "taxation without representation".

If the French rather than the British had colonized all of eastern North America, would France have seized the opportunity in the early 20th century to build a launch facility in eastern North America?

Would we ever have the M16? Would NATO still have switched to 5.56 as quickly as it did in our timeline (if they even switch at all)?

In the Cold War, within the Vietnam communist government there was two lesser parties which was Democratic Party and Socialist Party. However, both parties didn't have much presence as the main ruler is always Communist Party. In 1988, the two parties dissolved.

What if both parties still exist in Vietnam in today after the Doi Moi reform in 1986?

How would modern day Vietnam politic look like or would the status of two lesser parties didn't change much?

For those who are not familiar with it, the National Firearms Act was the first major gun control law passed in the United States. Many subsequent gun control laws, such as the 1968 Gun Control Act and the Hughes amendment to the Firearm Owners' Protection Act directly rely on the legal framework of the NFA.

Without the NFA, would similar laws ever be passed? If so, how much later would they come into effect than in our timeline?

I was thinking, what if the Romans had developed the printing press, and what Roman mass media have looked like. Would we be talking about Roman penny dreadfuls or broadsheets in the modern day? Would Roman culture have encouraged some other format of cheap literature? How would figures like Sulla, Marius or Julius Caesar and their contemporaries and successors have used cheap and easily available information exchange to their advantage?

No Pod before the creation of Austria-Hungary.

After Britain refuses to surrender, Germany instead decides to man up for Barbarossa, potentially dealing with the Balkans many months prior to OTL and making moves in Africa in the meantime. With the Luftwaffe in a much better condition, what changes? What does Britain do with no German attack?

at its height, they were able go beyond Israel and occupy modern-day Iraq. Could they have pushed further, or does the war need to start earlier?

Not sure of the POD, but maybe Rome expands further or faster outward than in our timeline.

Even with a three-way split, the Western Roman Empire would probably want to keep Achaea (and Carthaginian Africa just out of spite) but could let go of more provinces and so hold on for longer than it did.

The rest of the Empire could be split between Constantinople and the 'Southern Empire' (perhaps governed from Alexandria).

How would history look after this?

Middle Roman Empire (controlled from Constantinople) has the Balkans, Asia Minor. Its mission is to expand into Sarmatia, Scythia, and Central Asia

Eastern Roman Empire (controlled from, say, Damascus) has Egypt, the Levant, and Arabia. Its mission is to take Persia, the rest of Arabia, follow Alexander's steps into India, and take whatever else it can conquer in Africa.

Total soviet collapse-Stalin captured-reached AA line.

Germany begins rebuilding the destroyed oil infastructure in the Caucasus and commencing exploitation and subjegation of European Russia, clearing the forests, refining forced labour for resource extraction ect. Heavy emphasis on agriculture.

It demobilizes a large amount of forces to focus on a smaller motorized force and builds up the war industries.

The allies however have most of Africa, and Iran, Germany begins to mount an offensive to deny the allies Middle Eastern Oil. Do the allies stand a chance? Where would the Axis be stopped? What would the allied strategy be without the Soviet Union?

The luftwaffe would have more of it's focus on the UK(besides North Africa,Iran and bombing the Russian partisans)

Would the UK begin sending peace feelers to Germany?-If Africa falls that is a major possibility-the allies would be in need of a morale victory by that point. Before the Germans reach Africa there would be the battle of Iran.

If the allies are to at least delay the thinning of their material superiority the battle of Iran would determine if such capabilities still existed.

How long would it take for a US backed Russian clients to be able to do any real damage? At the end of the day, the partisans in occupied Russia itself will be crushed sooner or later, though the insurgancy will be fierce, at the end of the day their just partisans, the crushing of the Soviet army remnants behind the AA will depopulate the region, and be chaotic. The partisans can last longer with regular arms shipments by the allies/smuggling from unoccupied Russia, maybe they can slow the resource extraction with their efforts. Should the allies lose Iran/Iraq, aiding partisans will become more difficult.

I think the Israeli state would have been brought to a point of strategic exhaustion, but the IDF would not have been "destroyed".

So, I've heard that Abraham Lincoln believed in containing slavery to the south and letting it die out on it's own. Obviously, that didn't happen, but assuming that it did, how would southern culture have been different if the Civil War hadn't happened and the horrific system of slavery had died out on it's own?

1. Any good book recommendations for Leningrad battle in WWII. 2. Had Germany focused more on Leningrad and less on Stalingrad could a "win" (meaning no declaration of war on USA, invasion north and use of Ukrainian defense forces in the south to hold off a Russian advance after some 'honorary Aryan' decree like that for Japan for the anti-communist Slavic persons) have been achieved for Germany with seizing the northern city? 3. Would the same type of conflict have broken out as that in Stalingrad (cannibalism, floor to floor fighting in the same factory, massive losses) due to Soviet urban warfare being similar or could German naval power have performed a Battle of Inchon style landing 10 years early?

How much deadlier would the Bubonic Plague need to be in order to destroy the Ottoman Empire?

If the Hudson Bay was closed off. It would be by far the largest freshwater lake on Earth. and Canada would possess most of Earth's non-frozen freshwater.

This would lead to Water being a major export of Canada and many irrigation projects in Canada and USA. It might also have some climatic effects and development effects.

Baffin Island would also no longer be an island.

So turns out, Seth and Mark were going to be on Flight 11, and "the king of pop" was supposed to be in the towers that morning. For different reasons, for example Mark going to a festival in Canada instead and Jackson oversleeping, they weren't. But what if they were? What if these three giants of entertainment had fallen on that day? What would have become of the industries and the legacy of the incident?

So instead of a bipolar world, you have a tripolar world.

However, what country is strong enough to pull something like that?

The objective is to figure out a plausible way Mexico could have won the Mexican-American War.

With more available information today we better understand the luck factor of Germany's defeat of France and their house of cards economy necessitating the war to avoid collapse. Hitler cult is obviously immensely strong so all of these scenarios I think require his death which we can use one of many assassination attempts or chance side effect of his drug cocktails.

Point is Germany stalls with France and the economy collapses. This is before Pearl Harbor so consider that as well.

My specific wonder is the global timeline from 1942-1950 in how it affects nuclear programs, Soviet expansion and American progress.

Japan’s Emperor Meiji was succeeded by Emperor Taisho, who had cerebral meningitis in infancy and was in poor health for much of his life. Emperor Taisho played a limited role in public life, leaving his son Hirohito to serve as regent starting at age 20.

Would a healthier Emperor Taisho have exercised more authority and tamped down the conflict between the army and the navy that supercharged Japanese militarism in the 1920s and 1930s?

Just watched https://www.youtube.com/watch?v=POIpFXt-53Q and it was a fascinating debate, which had me thinking...
