To those reading this ;
1) yes it�s true anti Zionism isn�t a dad yachid but there were many many others who held Zionism has roots in our Torah.
2) There is no such rule or goal post that one needs to write or publish sefarim to refute another gadol. One can also commit actions that display their difference of opinion. And that stands just like publishing sefarim. In fact you only to publish a Sefer if you are anti Zionism. Because there is no action that you can take that displays anti Zionism other than writing a Sefer. The deeds of many pro Zionist gedolim are enough to prove that it has a source in our Torah.
3) There are actually a nice few pro Zionist Torah publications as well. Although yes as noted in #2 there are more anti because that�s the only way to express your view
Bottom line there are many holy gedolim pro Zionism
