The Chinese poet, literary critic, political thinker, and fearless dissident Liu Xiaobo—who won the Nobel Peace Prize in 2010—died last week while still under custody. He was imprisoned in 2008 for expressing opinions the Communist regime considered dangerous, and he had been arrested multiple times in the preceding two decades. In a 2012 essay, Simon Leys described his ideas and career:

After Mao’s death, universities were at long last allowed to reopen; in 1977 Liu joined the first group of students admitted again into higher education; . . . eleven years later, after obtaining his doctorate, he was appointed to a teaching post [at Beijing Normal University]. His original mind, vast intellectual curiosity, and gifts for expression ensured a brilliant academic career; quite early, he reached a large audience extending far beyond the classroom, and acquired the reputation of an enfant terrible in the Chinese cultural world. . . . Liu’s reputation as an original critic of ideas [eventually] brought him invitations abroad. . . .

While Liu was in New York [in 1989, teaching political science at Barnard College], the student [dissident] movement in Beijing continued to develop. . . . Liu sensed that a crisis would soon be reached, and he made a grave and generous decision: he gave up the safety and comfort of his New York academic appointment and rushed back to Beijing [to join the protestors at Tiananmen Square]. He did not leave the square during the last dramatic days of the students’ demonstration; . . . after martial law was imposed, he negotiated with the army in the hope of obtaining a peaceful evacuation of the square. . . .

At the [2010] Oslo ceremony, an empty chair was substituted for the absent laureate. Within hours, the words “empty chair” were banned from the Internet in China—wherever they occurred, the entire machinery of censorship was automatically set in motion.

Foreign experts in various intelligence organizations are trying to assess the growing strength of China, politically, economically, and militarily. The Chinese leaders are most likely to have a clear view of their own [considerable] power. If so, why are they so scared of a frail and powerless poet and essayist, locked away in jail, cut off from all human contacts? Why did the mere sight of his empty chair at the other end of the Eurasian continent plunge them into such a panic?

While I’ve seen much speculation—some reasonable and well informed, some quite the opposite—about why Jerusalem chose Friday morning to begin its campaign against Iran, the most obvious explanation seems to be the most convincing. First, 60 days had passed since President Trump warned that Tehran had 60 days to reach an agreement with the U.S. over its nuclear program. Second, Israeli intelligence was convinced that Iran was too close to developing nuclear weapons to delay military action any longer. Edward Luttwak explains why Israel was wise to attack:

Iran was adding more and more centrifuges in increasingly vast facilities at enormous expense, which made no sense at all if the aim was to generate energy. . . . It might be hoped that Israel’s own nuclear weapons could deter an Iranian nuclear attack against its own territory. But a nuclear Iran would dominate the entire Middle East, including Egypt, Jordan, the United Arab Emirates, and Bahrain, with which Israel has full diplomatic relations, as well as Saudi Arabia with which Israel hopes to have full relations in the near future.

Luttwak also considers the military feats the IDF and Mossad have accomplished in the past few days:

To reach all [its] targets, Israel had to deal with the range-payload problem that its air force first overcame in 1967, when it destroyed the air forces of three Arab states in a single day. . . . This time, too, impossible solutions were found for the range problem, including the use of 65-year-old airliners converted into tankers (Boeing is years later in delivering its own). To be able to use its short-range F-16s, Israel developed the “Rampage” air-launched missile, which flies upward on a ballistic trajectory, gaining range by gliding down to the target. That should make accuracy impossible—but once again, Israeli developers overcame the odds.
