I find this plot over time of US sympathy for Israel rather fascinating, especially when broken down by US party.
One has to wonder how much of that is explained by "conflict extension" in recent times, but that's not the topic of my question.
What I'd like to know: is there a country in Europe where a party's supporters express a similar level of sympathy toward Israel as the GOP's nowadays?
I was able to find a 2014 poll (but not a graph over time) for the UK, which does find some fairly significant differences across parties, but the pro-Israeli sentiment on the UK right doesn't rise anywhere near the US levels...
I cannot find any stats for Germany (but per comments and answers below pointing to right-wing populist parties) a news search has revealed that the AfD has joined the Free Democratic Party in a Bundestag effort to have Germany retract its support for UN resolutions condemning Israel.
