The war is going to a critical phase. Russia retreated after the culminating point(40 days). There is a change in strategy to concentrate on offense in Donbas while defending in the south. The crux of the Russia-Ukraine war is Donbas. NATO was providing lot of weapons from 2014, which Ukraine was using in Donbas. I guess Russia is now concerned about defending the south and trying to take full control of Donbas. The Russian retreat still looks fishy. There is something more damage planned on Kyiv. This may cause the war to enter more deadly phase with NATO getting more weapons to Ukraine and hitting Russian position inside Russia. Russia can create a fake chemical attack and nuke the Kyiv to bring the war under their control and to make NATO go one step back.
