On April 14, 1986, when the Reagan administration launched an airstrike on Libya in clear violation of international law, Kissinger did the rounds on news shows to justify the bombing. The day after the bombing, Kissinger appeared on ABC's 'Good Morning America' to voice his 'total support.' Attacking Libya, he said, was 'correct' and 'necessary.'
The question of causality is complex. For some philosophers and physicists, time might not exist. And since cause-and-effect reasoning needs the concept of time - of one thing preceding another - the effort to establish causality is a mug's game, an infinite regression of increasingly unanswerable questions.
If all Henry Kissinger contributed to the Middle East were a regional arms race, petrodollar addiction, Iranian radicalization, and the Tehran-Riyadh conflict, it would be bad enough. His legacy, however, is far worse than that: He has to answer for his role in the rise of political Islam.
