Financial and economic weaknesses are also working against Putin and his team from _within_ Russia.
> Just like we broke up the Soviet Union.
It was not entirely broken, since we have the living proof of it today in the Kremlin - same operating mode.

Why is he resorting to North Korean soldiers then? (which even then aren't infinite). Obviously, he has a problem at recruiting/training his own. Which puts him at odds with his own population.
So whose soldiers will it be next? China? not likely willing to deal with that. Iran? same. African countries? Not their war, they tell it themselves.
The issue is that Putin has cornered himself and his country, willingly, knowingly, into a no-way-out road. He had other options of both perspective and action.
