Biden provision of advanced artillery to Ukraine likely prompted Russian nuke exercise

From a piece on the Fox News website in which I was quoted:

Russia’s Defense Ministry announced Wednesday that around 1,000 members of its nuclear forces staged drills outside of Moscow following an announcement by President Biden that the U.S. is sending “more advanced rocket systems and munitions” to Ukraine.

“In the Ivanovo region, autonomous launchers of the Yars mobile ground-based missile system of the Teikovsky formation of the Strategic Missile Forces perform intensive maneuvering actions on combat patrol routes as part of the exercises,” the Interfax news agency quoted the Ministry as saying . . .

Rebekah Koffler, a former DIA intelligence officer and the author of “Putin’s Playbook: Russia’s Secret Plan to Defeat America, told Fox News Digital that the drills on Wednesday show that “Putin almost certainly is signaling to Washington that he would use his nuclear trump card, if Moscow thinks that it observes any indications and warnings that Ukraine is targeting Russia proper or if things are about to escalate otherwise.
