Since the start of Russia’s full-scale invasion more than two years ago, most of Ukraine’s international allies have insisted that any weapons they provide be used exclusively within Ukrainian territory. These restrictions were initially imposed to prevent a broadening of the conflict, but a growing chorus of critics now say this approach is preventing Ukraine from defending itself and risks enabling Russian victory.
The debate over the use of Western weapons to attack targets inside Russia has rumbled on throughout the war, and has recently been thrust to the top of the agenda by the Russian army’s latest offensive. In early May, Russian troops crossed Ukraine’s northern border and began advancing toward the country’s second city, Kharkiv. This attack was no surprise; on the contrary, Ukrainian military officials had been monitoring preparations on the other side of the border for weeks, but were powerless to act.
Russia’s Kharkiv offensive has highlighted the military absurdity of current restrictions on the use of the Western weapons supplied to Ukraine. Russian commanders are well aware of Ukraine’s inability to strike back, and are actively exploiting the border zone as a safe haven to concentrate forces and launch bombardments. Understandably, this is fueling calls among Ukraine’s allies for a major rethink.
