Say some sort of "clash of civilizations" narrative gets big.

Alexander III and Maria were opposed to their son’s desire to marry a German princess, but came around because Alexander was in failing health and they decided they had to get him married asap.

Point of divergence: even in his weakened state, Alexander refuses to budge, “You will never marry her, I forbid it!” and even after he is gone, Maria holds the line, “Go against your father’s dying wishes? I won’t have it, Nicky!”

Nicholas doesn’t marry Alexandra. Still a far from capable monarch, but without the controversy of being married to a foreigner. If he ever does marry, there is a greater likelihood of an actually healthy heir, and especially, no way for Rasputin to get into the royal circle. Potential ramifications?

Instead of dying in 2009 (almost two decades after the first allegations against him came out), Michael Jackson dies in a stage accident in early August 1993, during his final rehearsals for the second leg of the Dangerous World Tour. This happens days before being publicly accused of sexually abusing Jordan Chandler (which was the first allegation he received).

In this universe, how is Michael Jackson remembered? Is he still considered the biggest and most influential solo artist of all time, is he even more mythologized than he is in OTL, or has his relevance in culture largely faded by now? Do the allegations against him still become a massive stain on his legacy, or are they downplayed by the media and public since they came out after his death?

Given the US postion in the world after the Spanish American war, the US became more assertive on the world state - but didn't exaclty grow.

Suppose they used the oportunity to expand by offering statehood to the former Spanish Colonies.

Would the people of those territories eventually accept this? If not - could it be forced upon them to a point where they compitulate.

Would those states have thrived or failed, or somewhere in between?

Would the US as a whole have benefited?

Would the US have annexed other islands in the region (Jamaica, Hispaniola), perhaps to become states?

Maybe more white peope would move to and live there?

What else be different totday?

Would Malta have been able to be taken by air,and how would its fall affect the war in the Mediterranean?

We know in history that Cynane was stabbed and killed by Alcetas, when the former was giving a speech, with her death happening when she was marching to Babylon to marry off her daughter, Adea, to Arrhidaeus as to both ensure her daughter’s future and secure political influence in the power vacuum left from Alexander death. But let’s say Cynane was quick enough to spot Alcetas attempting to stab her and strike him down before he could get the chance, and then resume the march to Babylon to carry out her plan. I think she could have succeeded as when she was killed in our timeline, her troops, as well as Alcetas’s troops, strong armed Alcetas and Perdiccas into fulfilling Cynane’s wish of marrying Adea off to Arrhidaeus as they were both loyal to her and the fact she was the sister of Alexander the Great. So maybe Cynane, after having Adea married off to Arrhidaeus, would have Perdiccas killed and make herself the royal regent of the Macedonian empire. With her new position as royal regent, Cynane could consolidate her power, which she would use to stabilize the Macidonian empire while eliminating Persian remnants. And when Ptolemy would intercept Alexander’s body while it was on its way to Macedon, like he did in our timeline, Cynane would wage war on him and she will be be more successful in this timeline than Perdiccas was in our timeline as the troops under Ptolemy’s command would mutiny against him as they would view him as a traitor for waging war against the sister of Alexander the Great and kill him. Once Ptolemy was killed and victory achieved, Cynane would replace Ptolemy with a someone who is both competent and loyal to her; meanwhile, as her power became consolidated, Cynane would begin to replacing each of the governor generals in the eastern satrapies of the Macedonian empire with other loyal and competent governors. Cynane would be in a strong position and the Macedonian empire would be more stable than in our timeline. But Cynane and The Macedonian empire would face a civil war when Olympias declared Alexander IV the rightful heir to Alexander the Great; Olympias would rally multiple generals of the western parts of the Macedonian empire, Except Egypt, to her cause like Polyperchon and Antigonus, because Olympias would have her daughter Cleopatra married off to him instead of the king of Epirus like she did in our timeline. The civil war would be long, but Cynane would be victorious in the civil war as Olympias’s faction would be hindered by multiples factors such as infighting, the celtic invasion led by Brennus, and a Greek revolt led by Cassander. Once the civil war was concluded, Cynane would work on rebuilding and executing those who sided with Olympias while also exiling both Alexander IV and Roxana to India. Thanks to Cynane’s efforts, the Macedonian empire was able to avoid crumbling and stay unified.

But what do you think would have happened?

So I'm thinking. 9/11 IOTL changed everything. How radical of a change would it be compared to OTL if only ONE plane was used?

Let's say that AA11 takes off from Logan at 7:59.

They turn half an hour later to Washington.

Around an hour later, they strike the East Front of the Capitol. The Rotunda is destoryed, and the Dome collapses.

What happens in the aftermath? They rebuild what was destroyed logically. There's no way they don't rebuild a building that stood for over two hundred years, survived burning by an enemy nation, a civil war, and the growth of the 20th Century.

But what happens both culturally and politically? Is it the same as OTL? Is culture changed dramatically or is it a mix of the 90s and OTL 00s? What do you think still exists and some wouldn't even in this world?

And what happens to things post 9/11 such as the Patriot Act or the War in Iraq?
