In case you are not aware, the exact opposite happened.
To be clear, we very much do want Gaza. We had homes there. and we have Jewish roots there going back long before the time of today’s Palestinian colonists.
Above all of that though, is that we want peace. And so if we have to be patient for a time when we can peacefully live in Gaza again, we will be patient.
In the meantime, the most important thing is the safe return of loved ones who were taken hostage on October 7th (and before!) and safety for those living in rocket’s range of Gaza.

Google's Ngram viewer isn't working for the term "Ben Gurion Canal" for some reason, but it would show approximately when renewed interest started getting traction since the proposal was declassified in 1996.
I wouldn't be surprised if the 2021 Evergreen fiasco was contributory to this renewed interest but this is pure speculation on my part.
