The New York Times reports:

President Biden has authorized the first use of U.S.-supplied long-range missiles by Ukraine for strikes inside Russia, U.S. officials said.

The weapons are likely to be initially employed against Russian and North Korean troops in defense of Ukrainian forces in the Kursk region of western Russia, the officials said.

Mr. Biden’s decision is a major change in U.S. policy. The choice has divided his advisers, and his shift comes two months before President-elect Donald J. Trump takes office, having vowed to limit further support for Ukraine.

Allowing the Ukrainians to use the long-range missiles, known as the Army Tactical Missile Systems, or ATACMS, came in response to Russia’s surprise decision to bring North Korean troops into the fight, officials said.

Mr. Biden began to ease restrictions on the use of U.S.-supplied weapons on Russian soil after Russia launched a cross-border assault in May in the direction of Kharkiv, Ukraine’s second-largest city.

To help the Ukrainians defend Kharkiv, Mr. Biden allowed them to use the High Mobility Artillery Rocket System, or HIMARS, which have a range of about 50 miles, against Russian forces directly across the border. But Mr. Biden did not allow the Ukrainians to use longer-range ATACMS, which have a range of about 190 miles, in defense of Kharkiv.

While the officials said they do not expect the shift to fundamentally alter the course of the war, one of the goals of the policy change, they said, is to send a message to the North Koreans that their forces are vulnerable and that they should not send more of them.

The officials said that while the Ukrainians were likely to use the missiles first against Russian and North Korean troops that threaten Ukrainian forces in Kursk, Mr. Biden could authorize them to use the weapons elsewhere.

Some U.S. officials said they feared that Ukraine’s use of the missiles across the border could prompt President Vladimir V. Putin of Russia to retaliate with force against the United States and its coalition partners.

But other U.S. officials said they thought those fears were overblown.

The Russian military is set to launch a major assault by an estimated 50,000 soldiers, including North Korean troops, on dug-in Ukrainian positions in Kursk with the goal of retaking all of the Russian territory that the Ukrainians seized in August. [Continue reading…]
