Biden's latest move, as he prepares to hand over his duties, will infuriate Putin.

US President Joe Biden made one last move before handing over the presidency to Donald Trump. Biden allowed the long-range missiles provided to Ukraine by NATO to be used in Russia's Kursk region.

PUTIN HAD ISSUED A WARNING

Russian President Vladimir Putin had stated that he would consider the targeting of objectives within Russian borders by long-range NATO missiles as "NATO's official entry into the war."

STATEMENT FROM US SECURITY SOURCES

Speaking to the US-based Axios news organization, US security sources reiterated that this permission was granted only for use in the Kursk region of Russia, where active combat is ongoing and North Korean soldiers are supporting Russian troops.

THEY WILL NOT USE IT TO STRIKE CRITICAL AREAS

Ukraine will not be able to use these missiles to strike critical areas such as the capital Moscow. Sources indicated that this decision was made last Friday and was a retaliation for Russia bringing North Korean soldiers into the war. The US aims to intimidate North Korean soldiers with this move and plans to thwart the counter-offensive taking place in Kursk in this way.
