Its as if Putin want's a return to the old USSR & the Cold War with the West.
Making the threat to launch nuclear weapons shows he has no concept of his actions.
The West will rely less on Russian oil & gas and apart from India & China no one else will buy it.
If & when this situation changes Russia will have surplus oil/gas it can not sell.
And it will effect the Russian people & workers.
I see 3 oil bosses who voiced concern over Ukraine have fallen out of high up windows recently in Russia?
