The only thing that matters - in your opinion. Israel is actually pretty familiar with dual faced relations. Take Turkey, with Erdogan often having a go at Israel, whereas economic ties are less effected by this. Same goes with many ME Arab countries, even those officially not having relations with Israel, but a whole lot going on anyway (Saudi Arabia, previously the Emirates).
I think young voters grow older, become middle aged voters and moderate their views.
Again, poster was about a supposed 15 + years trend.
