You are on very thin ice with this claim. There may be no NKVD parades but you see war criminals like the sub commander who mudered thousands of women and children on the Wilhelm Gustloff refugee ship lionised as heroes in today's Russia.
Also, Russian histories make no mention of the mass rape and murders commited in Ostpreussen by the Red Army. Treating WWII war criminals as heroes is quite as much a Russian trait as a Latvian; indeed more so.
No kidding, there are parades glorifying the Soviet Communist Red Army all the time in Putin's Russia.
