evidence: Ukraine has seized back about 53% of its territory it initially lost when Russia invaded in February 2022, according to the Institute for the Study of War (ISW). Blinken claimed during a July 23 interview on CNN’s ‘State of the Union’ that Ukraine had taken back 50% of the territory it had lost since Russia’s invasion started in February 2022. [...] "Analysts can employ several methods to calculate control of terrain with varying results depending on the cartographical projection used and other factors. An estimate using ISW’s control of terrain data and the Mercator projection indicates that Ukrainian forces liberated about 53 percent of the land that Russian forces captured since February 2022," the assessment reads. "Estimates made using different data sources, measurement methods, or projections will generate different numbers. Factors, such as higher confidence about unconfirmed Russian claimed territorial gains, can impact such estimations as well."
