Which ones of those folks born there would not be citizens of the USA, if they were born in the USA (with apologies to Bruce Springsteen, of course.)?
They are the nation of Israel.
Israel is their home.
Correction, they are a nation which calls itself "Israel". Anything more than that is unprovable, i.e., "they are the Israel of prophecy". You can call yourself a tuna sandwich, but that doesn't make it true.
IMHO, the genetic aspect of Israel as Abraham's seed will be significant in regards to the fulfillment of prophecy.
I tend to believe today's political entity known as Israel is discernibly distinct from the genetic Israel, although many of the seed probably reside there and are the target of much adversity from unbelievers.
