In OEF, which country posed problems due to harboring enemies and difficult border terrain?

• A. Pakistan
• B. Iran
• C. Saudi Arabia
• D. India

Answer: (A)

The situation in OEF was shaped by two intertwined factors: sanctuaries for militant groups and the rugged border geography. Pakistan’s northwest frontier became a haven for Taliban and al-Qaeda elements, who could slip across the border, regroup, and move back into Afghanistan with relative ease. The border there is long, porous, and traversed by steep mountains and difficult terrain, making surveillance and interdiction hard and complicating cooperation with local authorities. That combination—harboring enemies and a challenging, hard-to-control border landscape—created persistent operational difficulties for the coalition in Afghanistan. Iran, Saudi Arabia, and India did not present the same pattern of cross-border sanctuaries and terrain along the Afghan front, so Pakistan stands out as the country described.
