A testimony only about his own speculation. Which should have not been taken as proof of anything.

a country « that was not Iraq » tried unsuccessfully to buy uranium yellowcake from Niger.

Apparently, that country was Iran. At least I read an article somewhere (I quoted the info to wchurchill) about what Wiklson reported, and it references another Nigerien official, one Mai Manga, saying so. (Had the intel process not been corrupted, an analyst would conclude that Manga's willingness to talk about Iran's attempt at purchase reinforces the truthfulness of his denial that Iraq has attempted such.)
