they're trying to keep the conflict going to keep the us involved at a time when the us has decided europe doesn't matter anymore.

Let's face it, Trump is the main problem here, not EU. If he had supported Ukraine by giving them sufficient military aid, Ukraine could have pushed the russians out of their land by now, and peace would have been achieved. But instead, no. He's trying very hard to be the biggest dumbass in the world's history.
