Michael H is living in another reality.
If a foreign army invaded my country and my city without justification, I would probably not use weapons personally.
I would perhaps "collaborate" with the enemy if I am forced to (but not to persecute minorities), while telling them that what they are doing is wrong, that they are not welcome here, and they should go home.
These kinds of "psychological" methods seem effective, when used by people like Marina Ovsyannikova (

Among "soft" methods to protect life, Zelensky could give the Russians officially Crimea and the two republics:
Ukraine: Putin will search for a way to save face

The loss of Crimea in 2014 is something Ukraine may well be forced to give its formal acceptance to, in some way. And Russia clearly intends to hang on to those areas in eastern Ukraine which are pretty much effectively under Russian control already - and perhaps more.

Donald Trump, in spite of his failings, might be one of the few in the U.S. who has understood this.
Now, the Ukrainians have decided to fight, and I don't blame them because they are not the ones who started this war.
For this fight to be effective, the Ukrainians need good weapons, in my opinion (I mean, beyond the Javelin and Stinger missile launchers), for example S-300 air defense systems (
