For Edward Luttwak, an Israeli strategist I never got to meet, but someone whose work Grand Strategy of the Roman Empire inspired a lot of thought, as did On Strategy, the point being that one can learn from history, especially when considering mega-strategic questions, like what to do with Iran now.
Caesar Augustus, also known as Octavian, was the great nephew of Gaius Julius Caesar.
Augustus is less well-known to most people, if he was the better man, becaus unlike Gaius Julius Caesar, Octavian was not an ego-maniacal adventurer, but a great statesman, if there was a sadness of his reign well-reflected in the poet Ovid he exiled to the Crimea.
There was a sadness to Augustus, because if the true glory of Rome, beyond Scipio Africanus' defeat of Hannibal, he was of the time of Kings, not Republics. That's what happens when the Power Elite doesn't solve a society's problem, as the oligarchy has to be compressed to a singleton.
Everything that has a beginning has an end, if that's a copout too.
Augustus was wise in particular in how he dealt with Iran, if it was called the Parthian Empire then.
The Parthians had chopped off the head of Great Uncle Julius Caesar's moneybags rival Crassus at the lovely battle of Carrhae in 53 B.C. (Carrhae is lovely because it was a beautiful demonstration of certain military possibilities of long range fire under ideal terrain conditons. Carrhae was a battle which cost the lives of 36,000 Romans, all of them there, and Crassus his head, plus the indignity of jis head then being used as a mask for the Parthian king's entertainment in the Greek play The Persians, ironically enough.)
The Romans had lost six standards to the Parhians at Carrhae, unacceptable for Roman honor, and for deterrence.
Because of Egypt's supply of oil, or rather grain, America, or rather Rome, needed the Middle East to have a certain order, not one to be threatened by Persians.
Julius Caesar was an ego-maniac who wanted to be Alexander the Great, who conquered Persians.
When he was murdered for putting the knife in the Republic by Brutus, whose family founded the Republic as to why, Caesar had assembled the largest Roman Army of all time, 15 legions, even a new one called Parthex, to avenge Carrhae.
Much time had passed after the death of his uncle when Augustus had the time to contemplate the right response to the Roman defeat at Carrhae, in which frankly that time was necessary for Augustus to order many fellow Romans to their death.
They were only other ambitious people willing to die for power, so one need not weep for the thousands killed on his orders.
But that left the last problem for Augustus, other than Germania solved by Varus carelessness at the Teutebourg Vald : what to do with the Parthians/Persians?
Caesar Augustus was wise, in understanding what Reagan talked about in terms of Peace through Strength When Dealing With Persians, and so assembled B-1s, B-2s, B-52s, carrier battle groups, alerted all nuclear forces, and then offered Iran, and Russia and China. a deal they , or Isreal, couldn't refuse, because it was reasonable for Rome to accept certain boundaries to its power at Tigres and Euphrates, as to how much influence Iran is going to have in Iraq: not zero as to security of travel to shrines, but zero Pasdaran either.
Najaf and Karbala are nice places to visit, except for Pasdaran, sort of like the Neutral Zone with the Romulans/ Persians.
Every emperor after Augustus who campaigned out of the the bounds set by Ceasar Augustus at best fought to a draw, save for the under-appreciated Dacian Wars, although Trajan and Aurelius were right to march out every now and then and burn tons of Persian cities to the ground when they didn't listen to reasonable proposals.
