>>511443580 (OP)It's impossible for Russia to attack the EU and NATO in 2027. The war in Ukraine will end in about a year with the rest of Donetsk oblast in Russian control. Less than 7000 km2 of Donetsk oblast is in Ukrainian control and Russia captures like 600 km2 per month. Russia will then spend years building new equipment and reforming their entire army with the tactics they've learned.
In the 2030's the war in Ukraine could resume with Ukraine's demographics in even worse shape from emigration and low birth rates. At that point Russia would aim for the eastern half of Ukraine to the Dnieper river or even more. War with Estonia, Latvia, Lithuania and Polish border regions is only possible 10 years from now and even then we don't know if Russia is interested in that.
