What is "afpak"

n. (context US English) Afghanistan and Pakistan considered as a single entity

AfPak (or Af-Pak) was a neologism used within US foreign policy circles to designate Afghanistan and Pakistan as a single theater of operations. The neologism reflects the policy approach introduced by the Obama administration, which regarded the region of Afghanistan and Pakistan as having a single, dominant political and military situation that required a joint policy in the War on Terror.

Following sharp criticism from Pakistan, condemning the perceived comparison of their country with Afghanistan, the US Government stopped using the term in 2010.
