The Bible produces some interesting insights into the Arab/Israeli conflict. They appear to have been fighting each other for centuries. Both trace their lineage to Abraham. Abraham had a son with the servant girl Hagar and he was called Ishmael. He then had a son with his wife Sarah and he was called Isaac. The Jews were descended from Isaac and the Arabs from Ishmael. It was said of Ishmael, “He shall be a wild man; his hand shall be against every man and every man’s hand against him.” Ishmael and Isaac have been fighting ever since. In AD 135ish the Romans joined the province of Judea/Samaria together with Galilee to form a new province Syria Palaestina. The word “Palaestina” was a reference to the Philistines, the arch enemies of the Israelites from the days of Moses. Rome had been fighting Jewish rebels and named Judea “Palaestina” as a sleight to the Jews.
I doubt that Carter or Blair will solve a problem that has several centuries of history behind it.
On the question of Iran, I do not believe that the current bout of sabre rattling will develop into conflict. The Iranians are not Arabs. However, history suggests that another Arab Israeli war is inevitable.
