Putin has got an "off-ramp" far too many times during his reign. He must face the consequences, though I'm highly doubtful it will ever happen (and it certainly won't happen if we get more of what Macron is saying should be done).
Macron is probably going to get a lot of flack for stating the obvious.
Yeah, sorry, we can't erase Russia from the map, we are going to have to deal with it, so maybe we can start building for peace now.
Also, what consequences ? We already seized their assets in Europe and US. Their army has been trashed, their credit score is lower than those of a median income household, and half of their male population is missing a bodypart, that's consequences aplenty already. In the meantime, NATO was revived from the dead, gained two prospective members, and Ukraine is probably joining Europe too.
Putting Putin
(haha) on trial would require to declare war on Russia, litterally nobody wants this, it's something we only do to small countries who can't defend themselves. And for no tangible benefit that we cannot achieve through diplomatic means.
Doing serious legwork is not as glamorous as going in cowboy style and bringing justice and democracy to Eurasia, certainly less macho, but franckly I'd take that option as soon as it's available.
Edit : Also, the war in Ukraine, as I see it, is the continuation of the Orange Revolution which is a transition from puppet state to actual democracy. This is why Ukraine must be protected at all costs. Ukraine wins, it's a successful long-term democratic transition secured, which is what we want. We have nothing to gain by attacking Russia.
