It would be great if somehow everything would be sorted out if "we" did the right thing (whoever "we" might be, and whatever "the right thing" is).

The "wrong" thing is to supply weapons including heavy weapons to be used against a population.
Iran Russia and China are doing that.

"We"?
I mean us. If we have a view on this we should state it.
I mean our governments who we should expect to try to establish what is the "right thing" or even just the best or least worst thing, and to persuade the international community to cooperate in doing it.
