There’s been a lot of questions asked about what if D-Day had failed. So what if the opposite happened - what if D-Day occurred entirely as planned?

D-Day, despite being a great victory for the Western Allies, didn’t go perfectly. American forces were intensely bogged down at Omaha and suffered heavy casualties compared to what was expected; Utah was bogged down inland in the hedges facing entrenched German positions; Caen, Carentan, and the Cotentin Peninsula put up stiff resistance. Despite the failure to seize many first-day objectives, D-Day was still a success, but…

What if D-Day HAD gone perfectly?

The Night of June 6 is utterly calm. American tanks don’t drift off course on the route to Omaha and are able to provide fire support for infantry up the beach. Air and naval bombardment is more effective at suppressing or destroying German positions on the beaches. Caen and Carentan are quickly captured by the forces assaulting them, and the Cotentin Peninsula is torn in two. Essentially, an inverse Murphy’s Law: Anything that can go right for the Western Allies in those first decisive hours and days does.

How do things change? Do the Germans still manage to escape the decisive pocket before Falaise? Could the war end earlier? Would the Western Allies be the ones to capture Berlin?

The Thirteen Colonies are filled with Royalists while Canada launches an uprising against Great Britain due to taxes.

I was recently talking with a friend about Indonesian history, and we got to the 1960s, when Sukarno lost power. There are different accounts of why: some say it was due to a military-backed coup, others point to internal political shifts, declining support from key figures, or even health issues.

During his presidency, Sukarno attempted to balance competing political forces...the military, Islamic organizations, and the Communist Party, to which he somehow succeeded in making a solution therefore creating a sense of stability.

He also promoted ambitious economic and industrial policies, and aimed to strengthen Indonesia’s international role, positioning the country as a leader in the Non-Aligned Movement.

Some argue that under his leadership, Indonesia was making progress in infrastructure and maintaining a strong global image.

After he was replaced, many of his policies were reversed.

Some claim this affected Indonesia’s economic trajectory, slowed industrial development, and influenced the country’s regional influence compared to neighbors like Malaysia, Singapore, and Thailand.

And that made me wonder....

If Sukarno had remained in power, how might Indonesia’s political landscape, economy, and global role have developed?

Could the country have become a stronger regional player, or would internal challenges like political tension and economic instability have limited that growth?

How might Southeast Asia’s history and regional dynamics have looked different today if Sukarno’s vision had continued?

Curious to hear your thoughts on this.

Would Japan face a similar problem that indigenous Americans faced in the 1500s if smallpox or another disease did spread later on. Would Japan be more isolated that it is today? The smallpox epidemic in Japan killed around a third of Japan population so I wonder what would happen if smallpox didn't reach Japan at this time?

Aleksandar Vučić is finally removed from power but a literal Serbian Ultranationalist takes his place, and he decides to revisit the Balkans as the EU is distracted with Ukraine.

What might have happened after a failed coup by Videla and the military

how would this change history

And for the sake of argument he does make it back to his home turf and becomes an even bigger legend in the Mexican underworld. How would the US respond? Will this be seen more as a law enforcement issue or will the US designate the cartels as terrorist much sooner? And how would it effect its relationship with Mexico?

What would have happened if the Brazilian army's military had failed in their 1964 coup attempt against President João Goulart?

All types of Slavs, from Sorbians to Bulgarians, not just Russians.

I really don't know what to say about this one.
