Putin really likes cool dates. 1st of June is not a random date, it is a Military Aviation Day in Russia, and they wanted to celebrate by bringing their heaviest bombers to a massive WWII Dresden-style raid before the "peace talks" to show their power and leverage. It was a pretty obvious move and on the 3rd year of ongoing war they got so careless they just exposed 30% of their strategic bombers fully loaded, standing still in the open and visible on every sat imagery for the sake of showing off.
