PUTIN's motivation is revenge for the Soviet Union's collapse.
We didn't even *try* to defeat the USSR, we just had to get Saddam Hussein out of Kuwait, and he assumed GHWBush was too weak to fight.
When the odds are 55:5, you don't assume that the 5 stand a chance, right?
Except Hussein's army was mostly Russian.
Socialism doesn't motivate people to do good work, it just threatens to punish the least productive workers (secret police + gulags).
