This article quotes the Chofetz Chaim, on the words "that the land not vomit you out" (Vayikra 20:22), where the Chofetz Chaim allegedly would say (according to his son):
“The Zionists err in thinking that keeping Torah and mitzvos is a side issue, having nothing to do with the mitzvah of living in Eretz Yisroel. But the Torah slaps them in the face, saying, “Let the land not vomit you out as it vomited out the nation before you.” This has already come true, and since then we have wandered in exile. Now we say, “Let the land not vomit us out, as it vomited out our forefathers.”
It is tracked back to כל כתבי חפץ חיים on page 74. The sefer is not available online. Does anyone maybe have a physical copy of this page where the Chofetz Chaim says this, and if so, what is the full context of him saying this?
