That is incorrect. The US tried to annex Texas, which had tried to declare independence from Mexico, which Mexico still viewed as part of its territory. So the US invaded Mexico first. US troops crossed past the disputed territory, and Mexican forces repelled them, seeing it as an attack. President Polk used this as an opportunity to declare full war on Mexico. He ran on a platform to annex Texas, so he was looking for any reason to declare war on Mexico, and was looking for a fight.
This information is literally available for free on the internet. James K Polk’a presidential platform that he ran on, was to annex Texas and expand the US by any means necessary. So he sent troops to the Texas-US border and had them engage in order to get Mexico to bite the bait, getting official permission from Congress to declare war. Regardless, declaring full blown war and stealing half of another countries’s territory simply for shooting as some soldiers is batshit crazy.
Pray tell, are you aware of what Texas’ position was in all of that? The dynamics at play there? You talk about imperialism as if it’s unique to the US and Europe, but that’s precisely what was going on with Mexico. They had subjugated Texas and effectively established military rule. It’s not as if US troops were there for no reason. And they did, in fact, respond to what constituted an act of war by Mexico. That is simply fact.
