This may be why Israel is preparing to go operational against Iran sooner rather than later.
Once these anti-aircraft missiles are ready, Israel would have a tough time carrying out an operation against Iran without help from the US (we can probably jam these)....help we all know they will not get from the Obama Administration (except maybe in October 2012).
When it comes to a choice of supporting freedom or slavery the Russians always opt for slavery.
Russia has a "red line".
Israel has hacked the S-300 already. The Russians know this. The hack can make one Israeli fighter jet look like fifty. The S-300 launches all its missiles at phantoms. Then the real attack comes.
