The Moscow proposal was communicated only to the US administration, as Russian officials are still refusing any contact with Kyiv.Russia previously announced a short ceasefire for Easter earlier in April. For Russian authorities, Victory Day has the same symbolic meaning.More than a victory fete, 9 May for Russia under Putin has become one of the most important holidays and a public demonstration of the Kremlin’s military power.This year, the show will be significantly scaled back, according to Moscow.The Victory Day parade would not feature military vehicles or cadets due to what the Kremlin described as “current operational situation”.
