So, targeting a major CBW development facility, and storage bunkers, affects Iranian interests? That could only mean vis-a-vis Israel. Because, it looks like, nasty as it is, only a few bottles of chlorine were used in this latest attack, regardless of how or who got them in place. Assad doesn't need major CBW against his population anymore.
Do you have a link for that the article what I saw earlier was about the Saudi’s committing money to East Jerusalem and the Saudis were concerned with how airstrikes would effect them in the region.
