Desai, then 93, was too ill to attend, but Kissinger appeared and testified that Desai had not worked in any capacity for the CIA. A Chicago jury ruled in favor of Hersh, finding it had not been proved that Hersh had intended to write falsehoods or that he had shown reckless disregard for the truth, either of which must be proven in a libel suit. After the Kissinger book, Hersh worked on the 1985 PBS Frontline documentary "Buying the Bomb", which reported on a Pakistani businessman who had attempted to smuggle electrical devices that could be used as nuclear bomb triggers out of the U.S. On June 12, 1986, an article written by Hersh in the Times revealed that U.S.-backed Panamanian dictator Manuel Noriega was a major figure in weapons and narcotics trafficking. The reporting was the first in a "political landslide" of revelations about Noriega; in 1989, the U.S. invaded Panama and captured him, bringing him back to the U.S. to stand trial. Hersh spent much of the decade writing two critically acclaimed but commercially unsuccessful books. In his 1986 title The Target Is Destroyed, Hersh examined the 1983 shootdown of Korean Air Lines Flight 007 by the Soviet Union. He reported that the U.S. Air Force knew almost immediately that the Soviets believed that they had shot down a military plane, and that the U.S. misrepresented the situation to portray the Soviets as deliberate murderers of civilians. In The Samson Option (1991), Hersh chronicled the history of Israel's nuclear weapon program, arguing that a nuclear capability was sought from the state's founding, and that it was achieved under a U.S. policy of feigned ignorance and indirect assistance. Hersh also wrote that Israel received aid from the U.S. in the 1973 Yom Kippur War through "nuclear blackmail" (Israel's threat to use the weapons against its Arab enemies). Another major allegation was that the intelligence passed to Israel by convicted American spy Jonathan Pollard had been shared with the Soviet Union by former Prime Minister Yitzhak Rabin, who denied the charge. Another allegation was that British media magnate Robert Maxwell was an informant for Mossad, Israel's national intelligence agency; Maxwell filed a defamation lawsuit against Hersh, but died in a drowning incident two weeks after the book was published. Hersh's 1997 best-seller The Dark Side of Camelot, about the political career of John F. Kennedy, was controversial and heavily criticized.
