Ukraine in search of its line of defense against Russia. Faced with the risk of a large-scale Russian offensive at the end of May or early June, Ukraine is seeking to establish a defensive line similar to the one that the Russians built to oppose the counter-offensive.

Ukraine is also engaged in a race against time to establish defensive lines worthy of the name in anticipation of an intensification of Russian attacks expected in May or June. The Ukrainian government began making a strong defensive line a top priority in November 2023.
