I can assure you the US and UK keep warheads much longer than that.The core stuff is plutonium which has a long half life. But they also use tritium or others as catalysts and they have a 12 year half life. So after 12 years only half the material is left and it might be a dud, depends on what they have tested and how much catalyst you need. It's all closely guarded secrets, but what I saw suggests the US is suspected of keeping stuff less than 10 years. And that if Russia has significant stockpiles of older stuff it might not go off. Seems plausible.
I suspect Russian warheads are perfectly serviceable
