Prediction:
Russia will eventually take over Ukraine, deny their rights, institute a Russian government, etc etc
Russia will gain a lot from taking over Ukraine’s economy (+China’s help), so any kind of sanctions placed (something that should’ve been done in the beginning) won’t do too much.
Sanctions will include taking out the Nord Stream pipeline which runs from Russia to Germany.
As far as a war, not sure if the US/NATO will declare a war over Ukraine only
They’ll most likely let Putin do what he wants unless something drastic happens
