Defense Government
Event Summary

Russia's Chief of the General Staff, Valery Gerasimov, announced that President Vladimir Putin has ordered the expansion of a buffer zone in Ukraine's Ukraine — Sumy Oblast and Ukraine — Kharkiv Oblast in 2026. Russian forces are reportedly pressing forward in northeastern Ukraine to establish this zone, which Vladimir Putin justifies as a defensive measure against cross-border attacks on Russian regions like Russia — Belgorod Oblast and Russia — Kursk Oblast. Ukraine, through President Volodymyr Zelenskyy, has vehemently rejected this plan, calling it 'mad' and a pretext for deeper incursions, vowing to resist any such actions. The 'North' troop grouping, formed in early 2024, is operating in northeastern Ukraine with the aim of pushing back Ukrainian forces and creating this buffer along the border.
