After the United States attempted to attack Canada in 1812 without success, it began to attack Mexico to the south in 1845, annexing California and Texas, and even entering Mexico City. But later it signed a peace treaty and withdrew, retaining California and Texas.

The treaty was not signed out of goodwill from the Americans, but rather because they suffered heavy losses from guerrilla attacks while occupying Mexico City. To put it bluntly, the United States at that time did not have the strength to fully annex Mexico.

So, the former emperor's venture was cut short, and today the world is divided into three parts, with Yizhou exhausted... uh, I misspoke, the American empire is still very strong, but it has indeed reached the geographical expansion limit.

To put it this way, I think the United States seemed to benefit everywhere during World War II, but in reality, it lost a godsend opportunity - to annex Canada and/or Mexico.

If the United States had annexed Canada and Mexico during the chaos in Europe back then, it would have meant its territory exceeding that of Russia, with a population of 500-600 million...

That would truly be a legacy for generations, the West's invincibility.

What a pity, there is no turning back 😂
