The Russians have always treated the Jews very well, beginning with the Pogroms back in Russia to the present day.
I'll venture Israel's attack date on Iran will be in part based on when these Missles are delivered to Iran. Russia is in effect forcing Israel to attack earlier, before these missles are in place, in Iran. May work out anyway, might just be the final straw that finalizes Israel's attack on Iran!
