Guys, we'd do well to recall this is real history, not a game of Oikoumene 3. The Carthaginians did nor emulate Alexander for the good reason that they didn't have to. Even their 'control' of the Celts, Lusitanians and Iberians did not extend much beyond a system of alliances, one-sided though they were. Yes, Carthaginian angeloi laid down the law as far as the Rhine and Elbe, but the Shophetim never claimed more than control over the landholdings in the Mediterranean. Even the Latin League was allowed a degree of independence. Why? Because it was the most effective way of doing these things.
Now, I personally don't think that a Roman victory would have presented the disaster some of you seem to envision. First, because the Romans were a lot like the Carthaginians. Yes, modern historians like to retcon the maritime Empires of our day to the past, but for all their naval tradition, the power of Carthage lay on the land of North Africa as much as that of Rome lay on that of Italy. The main difference lay in the far more primitive nature of the Roman concept of subject status, and even there, I think it wasn't significantly worse to be a Roman 'ally' than a Carthaginian. Of course it is doubtful the Romans would have been able to civilise the Celts, but then again, look at the rate with which Italy eventually Hellenised. They certainly weren't slow learners.
As to the question of infant sacrifices, I'm sorry but there is simply no excuse for that kind of behaviour in our day and age. We no longer live in the era of Hanno the Great. If you're not willing to change your views, you can at least spare others the pain. You know there is zygote sacrifice - yes, I know, you don't get the rush of hearing an actual living child sob with fear and scream in pain, in case that's what you're after, but Great Heavens, at least you're not hurting innocents! And please don't tell me the sky will fall - the Hellenes and Thinai have been doing without infant acrifice for over two millennia, and in case it has escaped your notice, they (not us) are the ruling powers of this world, culturally, militarily and technologically.
