To answer the title question I call upon history:
Philistines
Ammorites
Greek / Hellenistic Empire
Roman Empire
Assyrian Empire
Nazi Germany
Ottoman Empire
All have raised their hands against the Jewish people / nation. All have collapsed and yet the Jews remain. Those that do not learn the lessons of history are doomed to repeat them.
Oh you’re right, and you can throw Spain and Great Britain on there as well.
I hope we always support Israel. But in the end I think, IMHO, that they have God’s support. And you know . . . that kinda makes all the difference.
