Look at Thunderbird in AZ. Lots of diplomats and retired execs teach there and the focus is more of a practical international business MBA than a "theory" based MBA. It's fairly tough to get in, the curriculum is rigorous but you'll walk out with a solid skill set that can be applied and practiced. The only kicker is that while a second language isn't a requisite for admissions, it's strongly recommended.
Last time I checked, their curriculum involves working with local businesses and at least one foreign exchange program where you will work with an international entity is Asia or Europe. If it helps, they have been one of the top-rated MBA programs in the US according to numerous sources.
While Ivy League schools are excellent, you still are paying for a name. You'll easily pay double to triple in the "old guard" schools that you would at Thunderbird or the like. If money isn't an object or a concern, shoot for the stars. If it is, I'd pursue a more economical route. There are a number of top-notch MBA programs within the US that won't rip the shirt off your back and have you eating peanut-butter sandwiches for a decade afterwards...
