Ukrainian military strategy

1. Avoid frontal offensives because, in flat terrain, the number of tanks and soldiers matters. Russia would prevail. Ergo, on the frontlines, no offense but defense. A few kilometers east or west do not matter. The well-selected defense lines do.
2. Get good air defense so Russia’s rockets and missiles have a low chance of reaching the targets.
3. Hit targets in Russia, both military and infrastructure. Let Russians know that Ukrainians can destroy electric power stations in their cities, too.

Ukrainian military leaders seem to see it like I do. We can only guess when Russian elites will realize that returning to borders before 2014 is the only peace option. Will it be before the Russian Federation as we know it disintegrates or after that?
