Rare earths

China’s naked weaponization of rare earths brings to mind Mao Zedong’s "four pests" campaign, the old tyrant’s fanatical effort to exterminate all flies, mosquitoes, rats and sparrows, which turned into a spectacular piece of self-harm. Sparrows were always an odd choice of enemy, but Mao and his communist advisors reckoned each one ate four pounds of grain a year and a million dead sparrows would free up food for 60,000 people. The campaign, launched in 1958, saw the extermination of a billion sparrows, driving them to the brink of extinction. But the sparrows also ate insects, notably locusts, whose population exploded, and the ravenous locusts wreaked far more damage to crops than the sparrows ever did, hastening China’s descent into the deadliest famine in human history.

Donald Trump went nuclear. Before his meeting with Chinese leader Xi Jinping at an air base in South Korea, he ordered the Pentagon to test atomic weapons on an “equal basis” with China and Russia. Was Xi impressed? Probably not. While Russia expressed indignation, China did not permit itself to be distracted by Trump’s nuclear shenanigans. Instead, Beijing aimed to obtain economic concessions from a prideful Trump, which it did. From the outset, Xi sought to bring Trump down a peg, declaring that “both sides should consider the bigger picture and focus on the long-term benefits of cooperation, rather than falling into a vicious cycle of mutual retaliation.” Trump seems to have absorbed the lesson.
