It's not just Coke, though obviously they're an interesting case that's particularly close to home in e.g. Mexico. But many american companies have gotten contracts to privatize water resources and blatantly break the contracts, sometimes even providing people with worse water than what they were already getting.

However, I don't think any of that would have been possible without the american military, though to say that Coke is so successful because of military action is rather absurd. Yes, it's probably true, but Coke's actions are so far removed from the military action (that happened decades, if not a century, ago) that it's a little dramatic and silly.
