Is Ben&Jerry's that's old in Israel made locally? If so, it's made with cholov yisroel milk.
If not, is it cholov yisroel in Israel?
Apparently so. From the article linked to in the post above this one:
Ben & Jerry's ice cream in Israel is produced by an Israeli company, also named Ben & Jerry's, which is licensed to produce the sweet dessert. This Israeli company, which operates out of Beer Tuvia, is not boycotting any part of Israel. Their license only expires at the end of 2022.
