The amount of time lapse between when it was bombed and when they visit gives the Syrians plenty of time to “clean it up”.

Oh, yes, Syria can welcome a tour of an obliterated facility now that the site has been totally sanitized. Since there will be absolutely nothing to see there the IAEA can issue a report saying “we found no evidence of any nuclear program in Syria” — easy whitewash.

The Syrian story is far from over: in fact, on October 23, Al Seyassah ran a story about potential new secret nuclear sites in Syria. According to Western sources cited by the paper, it is possible that Syria is developing other nuclear sites with the help of North Korea, Iran and Iraqi experts, the latter who fled their country at the start of the Iraq war in 2003. In fact, observation satellites have allegedly located in Syria at least two other sites similar to the one destroyed by Israel last month.
Iran's handwriting is all over the wall from the chemical to the nuclear arms program in Syria. Indeed, in research conducted last year as part of an article published in Washington's The Examiner, this reporter delved into Syrian's secret nuclear program, making the point that Syria might actually be "Plan B" for Iran. By helping develop nuclear sites in Syria, strikes on Iran might turn out to be useless. This was a smart strategy until Israel bombed the Syrian nuclear site on September 6 and made the world notice.
A waste of time. The area got fully scrubbed and modified. Who is *hiting who.
