evidence: For months, the U.S. resisted sending Ukraine the long-range missiles out of concern that Kyiv could use them to hit deep into Russian territory, enraging Moscow and escalating the conflict. That was a key reason the administration sent the mid-range version, with a range of about 160 kilometers (roughly 100 miles), in October instead. [...] Like many of the other sophisticated weapons systems provided to Ukraine, the administration weighed whether their use would risk further escalating the conflict. The administration is continuing to make clear that the weapons cannot be used to hit targets inside Russia. At the State Department, spokesman Vedant Patel said Wednesday that Biden directed his national security team to send the ATACMS specifying that they be used inside Ukrainian sovereign territory. [...] The U.S. had refused to confirm that the long-range missiles were given to Ukraine until they were actually used on the battlefield and Kyiv leaders approved the public release. One official said the weapons were used early last week to strike the airfield in Dzhankoi, a city in Crimea, a peninsula that Russia seized from Ukraine in 2014. They were used again overnight east of the occupied city of Berdyansk.
