> air? the us has more than 3,000 combat air assets at their disposal; including the f-22, b-2, a-10, f-35, f-18, f-15, etc. mexico on the other hand, has miniscule combat air assets. they maintain a fleet of blackhawks and that's about it. their main workhorses are all turboprop planes. in total, around 300.  in terms of sheer air power, mexico is defenseless.  > navy? mexico has a frigate and other smaller boats, roughly 189 ships. the us has 470 ships. 11 of these are aircraft carriers. 2 carriers alone could own the skies over mexico and the other support craft will own the seas. gulf of america is not a slogan, it's an easily achievable objective.  > army? mexico has no heavy armor assets. none. no tanks or other heavy weapons systems. at best, they field light tanks/apcs and other support vehicles. they have maybe around 1,000-1,500 of these vehicles in use.  the us has 4,500+ heavy armor assets. the number of light armor is unavailable but could be estimated at at least the same number, if not double. manpower will mean jack shit for mexico if the us owns the skies, which they will. mexico's primary aa systems are sea-based, so submarines will make short work of them. mexico is fucked in an open war against the us. and, unlike afghanistan there are not a lot of weapons in mexico for the population to use against us occupation forces. it's not like there's a khyber pass making tons of small arms in that region.  the worst part will be the humanitarian crisis, as we'll be dumping deportees into an active warzone but, since it's technically not a "war", we'll have more leeway. i'm not exaggerating when i say that we'd be all the way to guatemala in 30 days or less. we ran that same tempo across the fucking ocean and baghdad fell in roughly that amount of time.  the mexican president is smoking crack if she thinks she can thumb her nose at the us.
