To answer the question of why the IAEA never inspected Isreal's nuclear site: the IAEA only administers the NPT. As long as Israel does not sign on to the Treaty, the IAEA has no authority over their nuclear facilities, and cannot do anything about them. The second question of possibly contaminated soil samples can be answered this way: when samples are brought in for testing, the IAEA labels the in such a way that the people doing the testing do not know from where they were taken. So the results cannot be influenced one way or the other. However, a similar situation occurred with samples that came from Iran, and the Agency was able to determine after investigation that they were the result of traces of material left on component parts that Iran had gotten from Pakistan. The moral of the story being that if the IAEA is allowed to investigate, they are able to find the source. By refusing to allow the IAEA to do further testing, Syria is hampering the IAEA in it's efforts to clear up the situation, and may even be violating it's inspections agreements with the IAEA. Paranoia is the wrong attitude to take when the IAEA is taking the required measures in tracking down the source of nuclear materials found at the site.

I should also like to point out that Iran is currently making a major effort to discredit Yukiya Amano, and I'm not surprised that Syria, being as close as it is to Iran, should suddenly start making these types of allegations which indirectly accuse Director General Amano of catering to nameless parties that are 'out to get' Syria.
