All throughout the post-war period, the Soviet Union kept the world from complete disaster and complete wildness.
The decision to remove the monument is an outrage and violates the obligations of the Czech Republic according to the 1993 agreement on amicable relations and cooperation.
This is a false claim and one of several disinformation cases about the statue of Marshall Konev in Prague. It is also consistent with common pro-Kremlin disinformation narratives about Russophobia and the supposedly hostile anti-Russian intentions of the West, based on which Russia can cast itself as the victim. In the dispute over the statue, Russia has argued that under the Czech-Russian mutual agreement of 1993, the Czech Republic is obliged to leave the statue in place on Prague's Interbrigade Square. However, this is an intentionally false and misleading interpretation of the terms of the agreement (full text available here). The monument is municipal property, belonging to city district Prague 6, and the 1993 agreement therefore does not apply to this case. The monument to Marshall Konev was erected in 1980 during the "normalisation" period in communist Czechoslovakia. The leadership of Prague's Municipal District 6, which retains legal ownership of the statue, has voted to move the monument to a museum and replace it with a memorial commemorating Soviet sacrifices in the fight against Hitler in general, and the liberation of Prague in particular.
