Historical Proof 1

An Enterprise landing party comprised of Captain Kirk, Scotty, Dr. McCoy, and Uhura are on the planet Halkan homeworld, attempting to gain rights for the Federation to mine dilithium on their planet. The Halkan leader, a man named Tharn, tells Kirk that while they find him to be believable, it does not change their overall position and that the Halkan Council cannot permit the Federation to mine dilithium on their planet. Kirk says that they have shown historical proof that the Federation's missions are peaceful.
