president Joe Biden allows Ukraine to strike inside Russia with missiles.President Joe Biden recently authorized Ukraine to use U.S.-supplied long-range missiles, specifically ATACMS, for strikes within Russian territory. This marks a significant shift in U.S. policy, as earlier restrictions prevented Ukraine from deploying these weapons beyond its own borders. The decision reportedly comes in response to North Korea sending troops to aid Russia in its conflict with Ukraine. It also coincides with increased Russian attacks on Ukrainian infrastructure during the winter months. The move has drawn sharp criticism from Moscow, with Kremlin officials warning that it escalates the war and could deepen U.S. involvement. Russian representatives described the policy change as a step toward NATO's direct engagement in the conflict. The U.S. administration faces concerns about potential retaliation from Russia, including cyberattacks or the provision of advanced weaponry to adversaries like the Houthis in Yemen. While Ukrainian officials have welcomed the decision, noting its potential to enhance their defensive capabilities, some experts believe it may not drastically alter the war’s trajectory. Many high-value Russian targets have already been relocated out of the missiles' range. The policy shift also comes as President Biden prepares to leave office, with President-elect Donald Trump signaling plans to reduce U.S. support for Ukraine.
