Since the start of the war, Ukraine has received more than €115 billion in military, financial and humanitarian aid from countries around the world. Now that the pendulum has swung, and the battlefield momentum is with Ukrainian forces, international allies have agreed to ramp up that support, with the US, UK and other major and minor military powers combining to pledge billions in weapons, ammunition and even modern tanks. But can that support go on indefinitely? As some countries run low on weapons stocks, will they cut off support to Ukraine rather than leave their borders vulnerable to potential attack? And will other factors such as rising energy costs, a looming global recession and the upcoming US presidential election determine to what extent - and for how long - international allies can fund Ukraine’s war effort?
