Re: Eastern Europe - I was referring to the Pew Research Center survey conducted across 34 European countries in 2015–17.

Re: attitudes of younger Jews I'm really referring to Non-Americans (Americans are a special case). With American Jews the age gradient effect is there, but I don't know about the impact of the last couple of years.

Take data points in Europe and attitudes are marked and there is data to support that Israel's recent actions are absolutely being rejected by younger Jews.

News media is considered more reliable in Europe over the US (by measures of the population) so that could certainly be playing into it.
