In its fight against Russian forces, Ukraine hopes to sever the "land bridge" of occupied territory linking Crimea with Russia (Christian Science Monitor, NPR, Wall Street Journal, see slide 2 for a map of the land bridge). The outcome will be determined using data as provided by the Institute for the Study of War's (ISW's) interactive map of Russia's invasion of Ukraine (ISW). For the purposes of this question, "Crimea" means the territory on the Crimean Peninsula marked as "Russian-controlled before February 24, 2022" on the ISW map, and "Russia" means the border of Ukraine and Russia generally recognized by the international community. The land bridge between Crimea and Russia will be considered severed once ISW reports that there is no longer a stretch of contiguous territory under Russian control between Crimea and Russia, be it "Assessed Russian Advances in Ukraine," "Claimed Russian Control over Ukrainian Territory," "Assess Russian-controlled Ukrainian Territory," or similar classification.
