So, this "game" of violence is justified as merely history?
It is ethically indifferent, it is not justified, it just is. The Romans won, period. That's why they had to say what was "right" and "legal" and what was not. The Roman law was the "right" law simply and only because they won on the battlefield, not because it was ethically justified or not. And of course life was better if you belonged to the descendants of the winners than the losers.
If I compare myself with a kid born somewhere in Ethiopia, or with a prince of Saoudi Arabia, there is no ethical justification why I'm much wealthier than that poor kid, and why that prince is much wealthier than I am. It just is. It is not a matter of merit or wrong choices. It is not ethically wrong either, it is indifferent, ethically. I have no ethical reasons to claim the fortune of that prince for myself, and the kid who is dying of hunger has no ethical right to claim my wellbeing either. At least, the rules are such.
In the same way, if the people making up a NEW nation (and clearly, in one way or another, they had to deal with the nation to which, by the rules, the land of that nation belonged to before) manage to make their rules hold within that nation, and have it accepted by others, well then that is then their nation. This has always been so, and will remain so.
So I find it total bull to justify, morally, the setting up of Israel because of some would-be historical fact 2000 years ago. But it is just as wrong to say that because such a justification does not hold, Israel shouldn't exist. There was no a priori justification for Israel to exist, but now that they managed to make it, as long as they can keep it, it has the same rights as any other nation. Because, at the end of the day, "rights" come out of the barrel of the biggest gun.
EDIT: (to continue my ranting :-) I think that what is sometimes considered as "ethical", "right", "lawful" and so on on a "modern, international" scale, is a kind of snapshot of the current situation as "boundary conditions" that is the "right" way for things to be. The current nations then are graved in stone, and "from now on we start to deal nicely with each other, only mutual agreements and business, no guns anymore". Although that is of course a solution that will avoid wars and bloodshed, it is also rather unfair to carve the current situation (which is a historical accident) forever in stone. Only a total redistribution of land and wealth over all people would generate true morally justified "initial conditions".
