Hello. First, the force of 100,000 Russian men is rather estimated by experts at at least 125,000 at different points on the eastern border of Ukraine, plus Crimea to the south, to which must be added the forces which will take part in maneuvers north into Belarus from February 10. Then, in addition to my previous answer, yes, we can count on a fairly strong mobilization of the Ukrainian population in the event of an invasion. Ukrainian national identity is stronger than in 2014, precisely because of the annexation of Crimea and the war in Donbass. According to a poll conducted in December in Ukraine by an institute of sociology, more than half of Ukrainians say they are ready to resist either by arms or by civil actions to a Russian invasion. We can assume that this resistance would be stronger in the western part of the country than in the eastern part, closer to Russia.
