In the article which bro islamirama posted, the jewish rabbi said they would be prepared to kill millions of palestinians right? I hope you don't mean that he is like ALL the palestinians? (i.e. that they are all evil?)
Alright, I will obviously have to bring this into context for you all, and before I do, in no way am I condoning such a statement.
This Rabbi has many political enemies, so Jewish sources may not always be the best to get it from either, however, from my understanding of what the Rabbi said, was the analogy that if
The state of Israel by rockets was ever threatened to be destroyed such as by a nuclear bomb or deadly gas bombs etc, than it would be okay by religious law to destroy all the Palestinians before all the jews in Israel were killed.
So in effect what he is saying, is that If 100 people are at risk in israel by a bomb that will be launched, and 100 Palestinians are in a building where it is to be launched in two minutes, what should Israel do? Well his opinion is the terrorists know what they are doing launching from areas with a dense population, and Israel must protect its own citizens.
For example; If A Nuclear Weapon was launched from somewhere in New York city to Mecca, and you knew about it. As a Muslim, are you destroying New York City before the launch the bomb which destroys Mecca or do you sit there inactive? Now lets say that New York has already launched bombs into Mecca but none Nuclear, and now the Nuclear one is coming. If its either Mecca or New York, I have no doubt 99% of Muslims destroy all of NY to save there own.
Of course, this Rabbi's opinion is very extremist like, and being "Chief Rabbi" means nothing since the current Chief Rabbi is no more than a puppet, and is actually in no position to make any judgments in Jewish Law. Example: the current Chief Rabbi; Rabbi Metzger:
Metzger has been seen as a controversial figure since his original election as Chief Rabbi. Many saw his election as having more to do with Israeli politics than religion. Metzger, who is not considered a halachic authority, is largely acquiescent to the rulings of Rabbi Yosef Shalom Eliashiv, a powerful figure in the Ashkenazi haredi community. Metzger is not recognised a posek and lacks the moral authority of his predecessor, Rabbi Yisrael Meir Lau. There is evidence suggesting that Metzger's election was orchestrated by Eliashiv, who wished to install a weak Ashkenazi Chief Rabbi as well as embarrass the NRP, whose candidate, Yaakov Ariel, had been expected to win the appointment.
But either way, I would expect Muslims to understand that in many cases you will have extremist clergy who urge to kill before seek peace. Islam has more than enough of them, and there is no denying Judaism has their fair share.
