edit: I just realized I may have misinterpreted your above statements, but I'll leave my comments below anyway in case they aren'tI'm biased of course, so grain salt, apply. That said, I'm confused by your plans simply because the short and long term seem to be so diametrically opposed. You essentially say you want to work anywhere, even in Zambia, but long term live in Texas. That strikes me as two rather divergent goals.
If you want to go experience an international lifestyle, try something completely different from Texas, and want to live in Europe (or Africa) for what could very well be MANY years, then LBS clearly gets you nearest to that goal. If you goal is to stay in the US, then LBS seems substantially less appropriate. I can't imagine there's a lot of Texas based recruiting opportunities at LBS.
This also ignores the rather important question of what your wife wants - both short and long term. That's a big deal because "Honey, guess what? Pack you bags! We're moving to Nigeria!" might not go over so well.
A final thought - if the attraction to LBS is just cause living in Europe for a while sounds kinda sexy, the other option is to do a study abroad for a quarter. You won't be guaranteed LBS, but there are a lot of really cool places to go. See:

Regardless, when you come up for admit weekend let me know, we can grab a coffee and maybe I can introduce you to some profs in the field (just give me enough warning so I can try to schedule).
