Putin annexing like Hitler did

Putin is due to annexe four provinces of eastern and southern Ukraine tomorrow. Just like that, as Hitler did when he annexed pat of Czechoslovakia in 1939. The provinces are Luhansk, Donetsk, Zaporizka and Kherson. The question is, what will Ukraine and what will the West do about it? There is still serious fighting going on in all four provinces, so will Putin say that any action taken by Ukraine against these provinces is the same as attacking Russia, giving him an excuse to launch a massive, possibly nuclear strike? Well, he did nothing when Ukraine launched attacks on military targets in Crimea, annexed by Putin in 2014. So I think it's all bluff. The Kyiv government is committed to recovering all territory taken by Russian troops. They cannot and will not stop fighting in these provinces, and Nato will continue to provide the weapons for them to defeat the Russians. So Putin's bluff will be called. The annexing of these four provinces is illegal, so the fighting will carry on. The danger is clear, however. The potential for a wider war, involving Nato in a more direct interventionist role is getting closer and closer. Are Joe Biden, Liz Truss, Emmanuel Macron and other Nato leaders ready for this?
