Actually, it seems that in Soviet times, the Russians would be willing/capable within their ROE and political system to do such a thing, and that is why they were not bothered by terrorism, domestic and foreign. That and the fact that the KGB were probably the instigators of a lot of terrorism against the West as part of the Cold War by other means.

Even in post-Soviet times, the Russians have staged some hostage rescues and shrugged off heavy hostage losses.
