They also wished to avoid comparisons to the Pueblo incident of 1968, where the failure to promptly use military force to halt the capture of a U.S. intelligence ship by North Korea led to an eleven-month hostage situation. Vice President Nelson A. Rockefeller insisted that "this will be seen as a test case... judged in South Korea." saying further "I think a violent response is in order. The world should know that we will act and that we will act quickly."[8]: 13  The Pueblo was not Secretary of State Henry Kissinger’s preferred historical analogy, however. Instead, he was thinking of the 1969 EC-121 shootdown by a North Korean military aircraft over the Sea of Japan. Kissinger thought the US reaction to the North Korean downing of the US Navy's EC-121 in international airspace with the loss of all 31 crewmen was exactly what they should avoid. Kissinger later told the security council members, "We assembled forces like crazy. But in the end, we did not do anything."[8]: 70
