Possible uranium enrichment going on in Iran

CNN is also reporting that uranium levels in samples taken from Iran are showing that it may be possible that Iran may be enriching uranium without having provided proper notification to the UN, and that the concentrations are significant enough to indicate that it may be weapons grade uranium.

Needless to say (but I'll be saying it anyway because I'm just like that), this is another area where we can't go jumping to any conclusions. How often during the war did we hear that preliminary tests indicated that something could be biological or chemical weapons only to later learn that, oops, it wasn't.

Again, it's something important to keep an eye on and see if we can find out what's really happening, but if the report is correct, it could indicate that Iran is working on nuclear weapons.

It does bring up a question, though.... if we can tell by examining these samples that Iran may be enriching uranium, and whether or not it would be weapons-grade uranium, then why haven't we heard anything about similar samples having been taken in Iraq or what the results of those samples are?
