Russia has legitimate commercial and Treaty interests in Syria.
We have no interests in Syria. None.
If Israel is not threatened and not squealing, why should we care what happens there?
What do you propose?
ANY threat that is not based solidly on legitimate, and known, US Interests will be seen as another Obama bluff. The MOST dangerous of situations.
Israel is not threatened by a Russia-Syria-Iraq-Iran-hezbollah axis?? Are you serious?
