First, it seems you are unaware of the Diaspora. (Have you read Philo and Josephus?) Second, do you think Cornelius was a Jew? Third, Paul explicitly states that Peter went to Antioch (Gal 2:11), which is not in Israel, but in Syria, clearly a "Gentile nation". The fathers also attest that Peter ordained Evodius in Antioch to be first bishop of the church there.

I know enough about it to know that the Northern tribes, dispersed to Assyria in 721 B.C., were never called Jews....they were referred to as "Israelites" and as you can see here they were even at war against the Jews. The King of Assyria [II Kings 17:6] dispersed them and replaced them with [II Kings 17:24] Babylonians, the land of Assyria encompassing quite a bit of territory at that time.
I didn't say Peter was an Apostle to the Jews....I said Peter was an Apostle to the circumcised (Israelites)....and the other eleven Apostles also. Antioch had, as well, been a part of the old Assyrian Empire.

It's funny that you should mention Galatians and Syria. The reason Peter was there was because Syria also was a part of the old Assyrian empire and many Israelites of the Northern ten tribes still inhabited the area. And, of course, this is where Paul makes his statement about the areas of responsibility.
