can destroy the house. The next year, Clark writes a memo to the CIA expressing his concerns over the rise of international terrorism since the demise of the Cold War, and recommends creating a NATO response team that could be rapidly deployed in terrorist situations. This special unit is created soon thereafter, with its base in Hereford, England. It is code-named Rainbow, and Clark is put in command of the unit with the equivalent rank of major general. In the book Rainbow Six, Rainbow is first put into operation. It responds successfully to three attacks by "Red" terrorists in Bern, Vienna, and Madrid. It also succeeds in defending itself from an attack by the Provisional Irish Republican Army (PIRA) against its home base. This is eventually determined to have been ordered by a radical eco-terrorist group, which Rainbow tracks down and destroys in the last pages of the novel. Clark's next appearance is in The Bear and the Dragon, where he is still the head of Rainbow. Initially assigned to train Russian Spetsnaz operatives, Rainbow is temporarily deployed to the Russian-Chinese war being fought in Siberia. In a joint Rainbow-Spetsnaz operation, he is involved in the destruction of China's only ICBM base. The operation is mostly successful: all but one of the missiles is destroyed, and the last one, while it is fired, is destroyed by the Navy before it can reach its intended target. Neither Clark nor Rainbow appears in The Teeth of the Tiger, but it is revealed that Rainbow is still operating. Prior to Jack Ryan resigning as President, Clark's Navy Cross was upgraded to the Medal of Honor. During the Medal of Honor ceremony Jack Ryan, Jr. was present in the Oval Office. Clark returns in Dead or Alive, in which he is part of a Rainbow team that successfully rescues all hostages taken by terrorists at the Swedish embassy in Libya. This proves to be his last act with the CIA, as he is pushed into retirement by Kealty political appointees. He then joins The Campus, an off-the-books intelligence agency that Ryan had founded before the end of his presidency. Clark is immediately involved with the organization's effort to find and neutralize "the Emir", an international terrorist leader modeled on Osama bin Laden, while also serving as mentor and trainer to Jack's son Jack Jr., a Campus analyst who wants to do fieldwork.
