At most, Zionism is the Yetzer Hara the same way that Shabbesai Tzvi-ism is the Yetzer Hara.
Perhaps, many years ago, Zionism was the Yetzer Hara, perhaps not. I have absolutely zero interest in getting involved in that debate.
Either way, as MDG alluded, in today’s world, Zionism is most certainly not the Yetzer Hara. It is merely a paper tiger which successfully distracts some people from the real struggles with which they should contend.
