the bad news for us all is that this is a vicious circle:
Russian economy falters, Putin's popularity weakens in Russia
Putin invades Ukraine to bolster popularity
War goes badly and economy shrinks 10%
Putin now REALLY needs a military victory to bolster popularity in Russia
Desperate military acts and major losses --> less popularity and more need for a military triumph ----> more desperate acts and losses.
Not looking good for any of us. Putin desperately needs to make this about NATO and not UKR so he will try hard to make it so.
