They seemed to be encouraging Ukraine to take the "offer" submitted by Russia. Total Ukrainian disarmament, no entry into NATO or the EU, Ukrainian recognition of the annexation of Crimea and the independence of Donbass.
I think that many of the older generation view Russia as inevitable.
They cheered Ukraine on at the beginning because they thought it would be short war anyway.
They cheered Ukraine on for the first week, because they thought Ukraine was going out in a blaze of glory.
They block transfer of aircraft because they think Ukraine will lose anyway and they think it might take too long to train up the Ukrainians, even on Soviet designs (because they've been upgraded with NATO-design avionics that Ukraine didn't have access to).
Now they propose surrender because they don't want to draw out the suffering that they feel will just lead to an inevitable win by Russia.
Russia is not inevitable. Russia may win this war - but that is far from certain. Very, very far from certain.
Ukraine is not collapsing and does not seem to be near collapse. Their military is bigger now than it was when the war started. This will go on as long as Putin is in power, and that could be for years - but Ukraine looks more and more able to keep up the fight for some time, years if need be. The NATO nations and other nations that work with them need to switch gears to accept that and start planning accordingly.
