The west has screwed this up, Putin has used the Hitler play book to perfection.
Get rid of anyone inside Russia that could stand up to him, test the water in the the years before today to see how the west reacts, attack another country under the pretence of "helping the Russian speaking folk, get a puppet state to fight alongside him. He has well and truly put the ball in our court with either we Help the Ukraine or we have to back down, he is banking on us backing down.
Hitler said he was amazed at how easy time and time again, we give him what he wanted, couldn't believe we didn't intervene, i think we have seen exactly the same with Putin, if we had showed some balls and NATO threated a hard response no way he would have attacked all of Ukraine, like its seems he has now, he may have tested the waters by helping the repels, but this is out there now, you cant disguise what this is. I think thats why we had a couple of days of him seeing our next move, moving a few troops into rebel controlled land, testing our responses all the time, which was to sanction a couple of people, that give him the green light.
No idea what we should do now, my heart says NATO needs to defend Ukraine to nip this in the bud now, my head cant get around what this could mean, is he crazy enough to use nukes? The time to stop this was weeks ago before shots were fired, gutted for the poor people of Ukraine, my heart goes out to them.
