There are huge consequences to Russia's failure to make this a walk-in invasion like Crimea. This is just one of them. Putin has fckked his only remaining ally to his West in Europe, alienated Kazakstan, and caused Finland and Sweden to apply for NATO membership. Not to mention being globally condemned and kicked off the UN human rights panel, and getting road and rail routes to Kaliningrad cut-off. In an attempt to gain, he has only lost.
Russia is yet to show its hands. Right now they are on the backfoot.
If things were this easy, the US would have made moves back in the 90s itself.
