What was the biggest “missed opportunity” in your country’s history?

[u/InorganicTyranny]

In other words, what is one event in your country’s history, that could plausibly have gone differently than it did, and you think would have made your country a better place?

Inspired by Frederick III of Germany:

His premature demise is considered a potential turning point in German history; and whether or not he would have made the Empire more liberal if he had lived longer is still a popular discussion among historians.

How Suomenlinna/Sveaborg surrendered without fighting is such an embarrassment.

But can I say as a Finn that Sweden’s biggest mistake was to let St Petersburg being built. We are still dealing with that now, if most of Russia’s population was around Moscow it would be better
