Let's say that the peninsular war never happened, Spain wasn't destroyed economically, politically and it's millitary wasn't in ruins and it kept it's colonies in the new world. How does this effect New Spain(Mexico) and US specifically? Keep in mind that this means New Spain controls Texas, California and the rest of present day south-western USA. Does the US still push to the Pacific trough Orego or do Spain or Britain manage to gobble it up instead? A lot of people left Spain for Cuba, Brazil etc. do they instead go to New Spain? Can New Spain attract other European immigrants and populate it's northern territories? US was willing to go to war with Mexico for this land, but would they be willing to fight a strong Spanish Empire? If you want extra spice what if Napoleon never took Louisiana from Spain in 1803 and Spain kept control of Louisiana territory as well? Or what if he took it but never sold it. Feel free to explore any of these 3 scenarios. Please don't get bogged down in why the peninsular war didn't happen and instead focus on the topic.
