The United States has granted Ukraine permission to use ATACMS missiles against Russian territory, marking a significant escalation in the ongoing conflict. This decision follows Ukraine’s prior use of British munitions to target strategic sites in annexed Crimea. The Ukrainian military aims to disrupt Russian logistics and command through long-range strikes. The political implications of this approval coincide with the imminent inauguration of Donald Trump, raising uncertainties about future U.S. military support. The use of ATACMS is expected to enhance Ukraine’s operational capabilities in the region.
