It is good to see that he is aware of this, and cares. "Romney: PA State Airspace Would Endanger Israel," from Israel National News, September 21 (thanks to Jan):
In Republican Presidential Candidate Mitt Romney's now famous “secret” video, Gov. Romney reveals and intuitively explains another existential threat to Israel from a Palestinian State in any part of Judea and Samaria.
He warns of the danger of Palestinian Arab State airspace 7 miles from Tel Aviv, abutting 70% of Israel’s Jewish population and 80% of Israel’s industrial base.
This is what Gov. Romney actually said:
"And then how about the airport? How about flying into this Palestinian nation?
"Are we going to allow military aircraft to come in? And weaponry to come in? And if not, who's going to keep it from coming in? Well, the Israelis. Well, the Palestinians are going to say, "We're not an independent nation if Israel is able to come in and tell us what can land at our airport."
These are problems, and they're very hard to solve, alright?"
