Who's side is Obama on?

During the uprising in Iran over the scam of an presidential election, in which many peaceful protesters were killed, president Obama went out of his way to keep silent about the whole situation. From the contested election results, to the murder of innocent iranian citizens who demanded to be heard by their government,Obama was conspicuously quiet about the injustices that were exacted upon the voters of that land. He said he didn't want to appear to be meddling in the affairs of another sovereign nation, however when it comes to Israel he has no problem with dictating to them what they should do within the borders of their own country.He told Israel that they should stop building settlements for jewish citizens on their on land It sure seems to me that he has no problem with meddling in Israeli affairs. He has broken his back to appease the muslim world, but clinched his teeth and talked very tough when comes to our closest ally in the middle east. I wonder if Israel needed America in a time of war would Obama respond favorably and decisively with Israel or choose not to "meddle" in our friend's business.
