The ISW made the assessment in its latest report on the war in Ukraine, published on Friday night, Polish state news agency PAP reported.
The Washington-based think tank said: “Russian forces are likely intensifying their strikes on Kyiv to stir up societal discontent in the capital, but these missile attacks are unlikely to break Ukrainian will.”
The ISW noted that "Russian strikes continue to pose a significant threat to Ukrainian civilians but are not improving the ability of Russian forces to conduct offensive operations in Ukraine.”
The US experts quoted Ukraine’s state electricity transmission system operator Ukrenergo as saying that “restoration of electricity may be delayed by the December 16.
“Ukraine’s United Energy System had to cut more than 50% of energy consumption as a result of the strikes,” the operator added, as quoted by ISW.
Saturday is day 297 of Russia’s war on Ukraine.
