This is an assumption on your part.

So you and the others are adopting the European strategy: don’t look for ways to end the war, just keep sending them guns.

No, that's no what they're saying at all. What I think they're saying is that the paths to end the war *NOW* have outcomes that 1. favor having more war in the future, 2. that Putin has never been known to be trusted on negotiations ( he has a pattern of extracting concessions, taking the concessions home, and not abiding by his obligations), 3. and there's no reason to believe he won't keep his pattern. So if we negotiate now, we have to include no more war in the future - which he won't abide by.

So we're better off continuing to supply Ukraine, which will stretch Putin out in the future - a year or two, etc., to the point where he becomes more willing to negotiate and leave. Even then, he will not honor any negotiations, so we have to build up Ukraine (along with the Euros), because Putin shows no signs of stopping his dream of rebuilding of the empire, and there's lots of little countries there.

If Putin dies or is somehow sidelined, this could change.
