But some U.S. officials and diplomats have said that the grouping is likely a ploy to dupe Ukrainian forces into diverting resources to defend against a possible incursion from the north, rather than focus on the south where Ukraine is making gains against Russian forces.Russia currently has “strained logistics” and is currently not able to stage offensive operations and is “only capable of defensive operations,” according to a British intelligence assessment released last week.When Russia claimed to have used hypersonics in the war in March, the British said the Russian claim was “highly likely intended to detract from a lack of progress in Russia’s ground campaign.”The news of their deployment to Belarus comes as Russia has been unleashing a barrage of missiles in Ukraine in recent days.Mayor Vitali Klitschko said Tuesday in a post on Telegram that the supplies had been restored, although the city will still use some “emergency shutdowns” of the power supply.U.S. officials have said they don’t expect Russia to let up on its attacks against civilian areas but are working on improving Ukraine’s air defenses."
