In a significant policy shift, President Joe Biden has authorized Ukraine to use long-range ATACMS missiles supplied by the US to strike within Russia, a decision previously resisted due to fears of escalating the war. This change comes as North Korean troops bolster Russian positions and ahead of Donald Trump’s potential return to the White House, raising concerns over future US support for Ukraine. While Ukraine may gain a tactical advantage, experts caution that the missile supply might not decisively alter the war’s trajectory. Russian officials, including President Vladimir Putin, have warned against such escalations.
