I think those pictures says it all.

Maybe another picture is needed, in which Ukraine can't unite on this, splits up and each side joins the group they prefer. Tragic, but it's happened to countries before.

And perhaps another picture, where Ukraine finds some new friends altogether!?

I think the truth of the matter is that you have to be part of an economic block these days, and have some solid allies. Wish it weren't so, but it is. Particularly for a "new" country like Ukraine.

What about Belarus?
We know that the EU absolutely HATES Lukashenko and is convinced that Belarus is completely undemocratic (I don't think that's necessarily true; there are different types of freedom - anyway it's the Belarussians problem, not the EUs.)

But Belarus is also not on the best of terms with Russia - so maybe Ukraine can also look at how to work closer with Belarus? Not exactly a substitute for the EU or Russia, but at least a "friendly neighbour".

Kazakhstan, Turkey, Iran are not too far away and not closely aligned to either bloc and might also be open for co-operation.
Not sure what Ukraine has to offer but no doubt, something.
(just thinking, if there is a third way for Ukraine, since the Russia-Ukraine-EU unhappy triangle drama has been going on for a decade now.
