If Ben Gurion offered a 60 year draft exemption (i.e. yeshivas allowed for 60 years, then no longer) – the Hareidim would probably have supported the plan to make Palestine into an American Trust Territory. Any significant Jewish opposition to independence would have tilted the balance. American policy is to leave self-contained peaceful religious minorities alone.
Note that the zionists aren’t discussing defunding yeshivos, but of seizing the students and their money, and seizing money raised in America so it can’t be used to support students learning Torah. Even the British and Muslims never did that. So this means Lapid and Bennett are more in a class with the Crusaders and Romans as enemies of Torah.
