Today’s young activists absolutely hate Bono, says Ian Leslie in his Substack newsletter. They think brokering deals between elites is “irrelevant and corrupting”, and a distraction from the all-important work of “systemic change”. But it’s dealing with elites – some, like George W Bush and Bill Clinton, now pariahs among the woke youth – that has allowed Bono to achieve so much. Take Aids. By working closely with Bush, going on Oprah, touring Republican states with his band, and flying back and forth to Africa, Bono convinced the US to announce $15bn for Aids relief in 2003. “Until Covid-19, it was the largest-ever public health intervention against a single disease.”

When British forces first used the Maxim machine gun on the battlefield, in present-day Zimbabwe in 1893, it fundamentally changed the nature of warfare, says Mark Bowden in The Atlantic. By World War I, machine guns had “driven infantry underground”: armies fought from deep trench networks spanning “the entire European continent”. Something similar could happen with drones. Small, cheap, and difficult to shoot down, drones have already played a huge part in the Ukraine war. They have been used to attack Russian ships in the Black Sea, and to “debilitate” Ukraine’s water and electricity grid. But military strategists think this is just the start.
