US President Joe Biden has authorized Ukraine to use long-range ATACMS missiles against Russia, marking a significant shift in US policy. Ukrainian President Volodymyr Zelensky has been advocating for this change, which comes amid escalating tensions with Russia, including the involvement of North Korean soldiers. The decision is seen as a strategic move to bolster Ukraine's defense and maintain territorial gains. Biden's approval also paves the way for Britain and France to provide additional missile support. The ongoing conflict has seen increased Russian drone strikes and significant casualties.
