There are many nerdy alternatives to March Madness, including Foreign Policy’s “Democrats vs. Dictators” playoffs (check out last year’s here) and Public Radio March Madness. But perhaps our favorite is Twitter Fight Club, which is an annual jousting tournament between Twitter’s best foreign-policy and national-security wonks. Foreign policy! Banter! We’re all over it.

#TFC13, as its friends call it, is also an excellent opportunity to beef up your Twitter stream when it comes to defense, Middle East politics, the UN, and other issues. Just take a look at the bracket — or this list of contestants — and follow accordingly.
