The Obama administration appears to be conducting a campaign of leaks to the media to stop Israel from attacking Tehran's nuclear program. It seems Obama fears an Israeli military strike more than he fears Iran achieving nuclear-weapons capability.
Obama appears to be hemming in Israel at every turn. Case in point: A report in which unnamed US officials allege that Israel has obtained access to bases in Azerbaijan, on Iran's border.
Be forewarned, Israel and the US. We are entering a dangerous stage in which Iran feels it must respond in kind to attacks against it. When two nations engage in patterns of attacks and counterattacks, it's much easier for a mistake or misjudgment to lead to disaster.
