CIA analyst Jack Ryan, who has studied Nemerov and believes him to be a reformer who merely talks like a hardliner to gain their support, is summoned by Cabot to accompany him to Moscow to inspect the top Russian nuclear weapons facility, in compliance with the START treaty. At the Kremlin, they meet Nemerov and his personal aide, former KGB agent Anatoly Grushkov. He requests they deliver a personal message to Fowler, asking him and the US to remain out of Russia's war in Chechnya and letting Nemerov stabilize Russia in his own way without outside interference. During their investigation of the weapons facility, Ryan notices the absence of three scientists listed on the facility's roster. After receiving reliable intelligence from a confidential secure informant inside the Kremlin, codenamed "Spinnaker", Cabot sends operative John Clark to Russia to investigate.
