They just want the good days back.
German exports have increased to the countries the surround Russia. Britain is doing the same with things like drone equipment and heavy machinery
The average age of a Ukrainian solider is 40 if not older and they have loss lots of ground that they will unlikely be able to take back. Western “support” was increasing arms sales, destroying Ukrainian labour and pushing more privatisation in that economy.
On the Corbyn point. Ex British military talked about a coup if Corbyn won and serving British soldiers used pictures of Corbyn as target practice. Had Labour won in 2017 or 2019 then the British state and the capitalist class would have wholly shat their brains out and caused a political and economic crisis.
With a Corbyn led Labour government we wouldn’t have never got to stage of pretending a prime minster job is deciding how many times to hit help Ukraine button.
