The pre-67 borders thing is irrelevant BS. Unless the USA wants to return Texas and California to Spain, they have zero room to talk about expansion by conquest. Especially a reluctant, almost embarrassed expansion due to winning an unexpected war.
imho, . . . to push things perhaps further into absurdity . . . perhaps not . . .
We could go back to the Romans taking Israel's land from them after 70AD.
And, long before that God Almighty gave them the land from the Canaanites . . . folks who wish to argue with Almighty God Yehovah are welcome to do so but I don't recommend it.
Considering that God says the whole earth is His . . . I figure He can give portions of it to his Buddy Abraham and descendants if He wants to. And He clearly wanted to.
He will also end up protecting it and expanding it to what He promised Abraham and David. They have NEVER taken possession of all that geography.
They WILL.God will wipe away a lot of Arabs but then he will build them back up, as well . . . after they realize who's truly Boss.
