I don’t know international law but it seems a bit like an act of war to send in troops without the request. Right now Mexico is basically sending in their own military like units. They actually had to build one up from scratch due to corruption in existing police and military orgs. At some point I could see it being in the US interests to give aid if requested but yeah just strolling over the boarder 1864 style is probably a bad idea.

Which is important to emphasize. Military involvement would only be acceptable if Mexico agreed to it.
