Here is what Ukraine probably wants from its wild assault on Russian territory

Matthew Savill, director of military sciences at the London-based Royal United Services Institute, assessed on Monday that some Russian troops had been moved from within Ukraine, but the scale is unclear. Savill also suggested that the attack may be connected to other undeclared efforts, either as a diversion or as a supporting fight. For example, it could be intended to weaken the supply lines supporting the remains of the Russian forces left over from Russia's fumbled attack on Kharkiv earlier this year, he wrote in an assessment seen by BI.
