Some of the Hasids and other "Ultraorthodox" Jews --- even in Israel --- don't believe the present-day state of Israel is the nation of Israel predicted in prophecy. This is because it's a secular democratic state which does not require Jews to keep kosher and follow the Torah.
Yeah, lots of people are mistaken all over the water front! LOL.
And, it isn't the State God is intent on establishing fully IN HIM. But it's a lot closer than it was during WWII.
