I agree that it's not progressives that enable or embolden Hamas. But I do think you're not taking into account Judaism's peculiar status as more than a religion but less than a race. Zionists were originally, & to an extent still are, very secular. They envisioned a secular, democratic state with a Jewish majority where Jews of any sort would be welcome. Are secular, democratic & eternal Jewish-majority contradictory? Yes. But I think they hoped that in the one tiny sliver of land they had chosen the world would overlook these contradictions.

Perhaps they failed to foresee the Middle East taking over the Balkans's role of creating more politics than could be consumed locally.

Secularism, in fact, is one of Israel's principle contradictions. When Dayan ceded control of the Temple Mount to Muslim authorities, some said he was naive. I believe he did it to prevent, or least delay, the looming conflict over Israel as a secular democracy vs. a halachal state. Rebuilding the Temple would certainly be the key step in the creation of the latter.

That is why some believe Israel, like Hamas, seeks to keep their own conflict ongoing. If they're fighting Hamas/PLO/Hezbollah/etc... they're not fighting one another.

Not only do the secular Zionist originalists face an Arab demographic time bomb, they also face one from the ultra-religious. Hard to be optimistic under circumstances such as these.
