The US has allowed Ukraine to use long-range ATACMS missiles for strikes inside Russia for the first time, reversing a previous policy due to fears of escalation. This decision comes as President Biden prepares to hand over power to Donald Trump, who is skeptical of military aid to Ukraine. Ukraine has been using these missiles against Russian targets in occupied territories but was previously restricted from using them inside Russia. The policy change is seen as a response to North Korean troop deployments in support of Russia. Ukrainian officials expect a counter-offensive from Russia and North Korea, and the supply of missiles may not significantly alter the war's dynamics. Concerns remain about the quantity of missiles available and the potential psychological impact on Ukraine.
