Mission Brief[]
"Interrogating the high-ranking government official revealed some valuable information regarding the leader of Uruguay and his weakness for poker. Send a diplomat to meet with him on some trivial pretext, and then challenge him to a friendly game of poker once the "business" is out of the way. We'll cheat, of course, but he won't be able to stop until he owes us the equivalent of Uruguay's GDP. He'll then have no choice but to grant use a seat on the S.M.A.S.H. council in return for calling off the debt."
