No. You are so very wrong. I am horrified that anyone would say such a thing. That is defeatist talk. Not only that, but it is very dangerous talk. Such talk incites the wrong people to act wrongly. Putin already took over control of Belarus peacefully, earlier this year. The Belarusians may not realise it yet, but they have been taken over. Putin told them they have the same rights of passage as Russians. Aren't they lucky!!!
You have to spread the map out and look further afield to what is taking place.
Last year Putin announced conscription, and thousands of Russians of military age fled to Georgia. Now Georgia is not a NATO country, but it does enjoy some of the benefits. It is not a member of the EU. However, just as Russians settled down in the Donbas and gave Putin the excuse to ''protect the interests of Russian people there'', so have Russians settled in Georgia as immigrants, and they too will become an excuse for Putin to invade when it suits him.
It might suit him sooner or later, because he wants to control a bit more of the world shipping in the Black Sea. He has already invaded most of the Black Sea coast of Ukraine, and is obviously making a claim to Odesa, the vital link for Ukraine's grain exports, especially vital to Africa. Putin and Erdogan will not make a move without the other one knowing, so international shipping through to the Mediterranean Sea could be compromised.
That shipping can no longer go through the Suez Canal, because Iran is funding not just Hamas and Hezbollah, but the Houthis down in Yemen, who are targeting international shipping in the Red Sea. Now goods have to go round Cape Horn, increasing prices. South Africa, with all it's gang warfare, tried to intimidate that route by accusing Israel, but they have no sense.
Why does Putin want Ukraine? He wants the mineral rights. He will lay Ukraine to waste - a no mans land, like the area between the Berlin wall and the people of East Germany.
