"You never get quite down to the bottom of the barrel, but we are much higher than that at the present time. There is quite a lot left in the barrel that could be explained by them. If they have some weapons, if they have some anthrax, they should deliver that"

Hans Blix, a Swedish diplomat and previous head of the United Nations Monitoring, Verification and Inspection Commission (UNMOVIC), made this declaration in the context of conversations surrounding weapons assessments in Iraq before the 2003 Iraq War. The quote is reflective of the complex process of arms examinations and the challenges faced in validating a country's disarmament claims. Below is an analysis of the crucial elements of this statement:

1. **"You never get rather down to the bottom of the barrel"**: This metaphor recommends that, in the process of evaluations, there is frequently recurring uncertainty. Inspectors might not be able to validate with absolute certainty that all weapons or materials have actually been represented, akin to not being able to see every corner of a barrel to ensure it's empty. This might be a commentary on the intrinsic limitations of the evaluation procedure, where inspectors might not have access to all sites, documents, or cooperation essential to completely confirm disarmament.

2. **"We are much greater than that at the present time"**: Blix is most likely suggesting that the situation, although not completely fixed, is presently in a reasonably positive state. The evaluations have actually yielded outcomes that are better than simple unknowns or baseless speculation. It suggests some development in discovering information or compliance from Iraq concerning disarmament.

3. **"There is quite a lot left in the barrel that could be explained by them"**: This part of the declaration recommends that the Iraqi government still had explanations or justifications to supply about their weapons programs. In spite of progress in the assessments, many concerns or unpredictabilities remained-- like the unknown "contents" left in the metaphorical barrel. It indicates that Iraq required to use more transparency or info.

4. **"If they have some weapons, if they have some anthrax, they must provide that"**: This is a require full cooperation from Iraq. Blix may be emphasizing the need for Iraq to honestly provide any staying weapons, such as anthrax, to inspectors to clear any ambiguities and verify compliance with disarmament responsibilities. In essence, it's a request for Iraq to demonstrate its peaceful intents and fix impressive issues with concrete actions.

Overall, Blix's quote highlights the intricacies of the disarmament process and the obstacles in ensuring comprehensive compliance in worldwide arms inspections.
