This raises the question of what comes next if this kind of thing keeps happening. What does Russia do? Russia appears to have staked the farm on this operation. Can it afford anything less than total victory?
The Russian military has made a sizable investment in tactical nuclear weapons with allegedly 2,000 of them on hand [1]. These small weapons can be detonated in ways that produce minimal fallout but lots of destruction [2]:
> A tactical nuclear weapon (TNW) or non-strategic nuclear weapon is a nuclear weapon which is designed to be used on a battlefield in military situations, mostly with friendly forces in proximity and perhaps even on contested friendly territory. Generally smaller in explosive power, they are defined in contrast to strategic nuclear weapons, which are designed mostly to be targeted at the enemy interior away from the war front against military bases, cities, towns, arms industries, and other hardened or larger-area targets to damage the enemy's ability to wage war.
With every conventional defeat faced by the Russian military and with the massive loss of credibility this causes, at what point does Russia decide that it's time to take the gloves off?
