There is a path to a peace agreement. Obviously these wouldn't be unilateral actions, but offerings or part of a final agreement with concessions on all sides:
- no NATO membership for Ukraine (it has already been invaded, there is no loss in taking this position now, and much to gain even if it leads to Russian withdrawal)
- some wider security agreement for the region -- if this means no more events like the NATO bombing of Serbia without UN authorization, that is perfectly acceptable
- repeal of discriminatory language laws, etc., and implement some meaningful degree regional autonomy for eastern parts of Ukraine (and western if they want it), basically Minsk 2 clause 4; or some internationally observed (so not like Crimea) referenda in those regions
- relax and withdraw most/all sanctions, but absolutely those on the central bank and SWIFT (though Russia will obviously and rationally accelerate economic links outside of Western control, as will many other countries)
I think a crucial condition should be no imposed change of government in Ukraine (so like what Russia wants in its military intervention in Syria, and not what the US wanted in military interventions in Libya, Iraq, and wants in Syria, etc.)
As for supporting Russians, I totally agree. One of the problems with the sanctions is that they are going to hurt ordinary Russian people, and are just as likely to strengthen the authorities as much as "encourage" ordinary Russians to change their government ("encourage" through collective punishment). The long legacy of Cuba, Venezuela, Iran, Iraq, etc., shows that this tactic far more often just hurts and even kills ordinary people rather than anything else.
There are many news pundits and analysts with prominent positions and exposure in print and television news in the US, who say things like, "There are no neutral Russian citizens now, they are all responsible for the invasion now" (this is paraphrasing, but not an exaggeration), at least on their personal twitter feeds. Unfortunately, I think most of the focus on "internal changes" is focused on severe collective punishment of ordinary people, rather than anything else, and so I find most of it counter-productive and cruel.
