I didn’t say they weren’t politically powerful. The two main Haredi (Ultra-orthodox) parties are significant part of Netanyahu’s coalition, and they have always had a disproportionate power compared to the Haredi population because almost all Haredi voters vote for them.
Within the Haredi community there is still a wide range of opinions, of course. However, even within Israel most have not traditionally described themselves as Zionists (only 33% percent, according to a 2016 survey).
