Putin's weapons packed with U.S.-made microchips, can Russia go it alone?

Ukrainian intelligence: U.S.-made microchips found on captured or destroyed Russian military equipment. 'The War Zone' - Ukrainians found Russian forces' strong reliance on foreign microchips. Foreign-made microchips found in Pantsir air defense system, Ka-52 attack chopper & Kh-101 cruise missile. The lists provided by Ukrainian intel raise questions about Russia's ability to produce key tech components. 5 U.S.-made chips in Pantsir air defense system, 35 in Kh-101 cruise missile & 22 in the Ka-52 attack chopper. The microchips would not necessarily be sourced directly from the manufacturers. Unregulated market for recycled chips, largely emanating from China, & many of them seem quite old. U.S. Commerce Secretary said Russian equipment filled with semiconductors taken out of dishwashers & refrigerators.
