Didn't think to look at the answers being filled in, otherwise I would have realised that they were in alphabetical order and may have got the few I missed
Israel and Lebanon were the last two I picked up, as well. Israel almost had a border with Saudi Arabia, but the Saudis decided that Israelis had cooties and so gave up part of their territory to Jordan allowing Jordan access to the Red Sea while saving Saudi the embarrassment of touching Israel.
I don't think Iran borders any of the countries in orange, so I don't know why it is not on here. The closest countries to it are China, Saudi Arabia, and Turkey, but none of those actually border Iran.
But VERY fun! Thank you.
