Brazil and weapons of mass destruction

Based on Brazil's history, it's belived that the country has no or insignificant weapons of mass destruction.

In 2004, there were a initiative from UNO to inspect the instalations where the enrichment of uranium-238 is made, verifying if the process was not used for building nuclear weapons. This was partly denied by Brazilian authorities, which has not allowed the inspection near the centrifugal machine. An authority said there are industrial secrets in the centrifugal process which led to a much cheapier enrichment (from 10 to 100x), and they were not willing to show this procedure to non-Brazilians.

On the other side, some USA's authorities stated that a tecnique like this "could not be so good", althought USA had stopped researching ways to enrich uranium some time ago. They belive the inspection should be made to garantee there is no nuclear weapons being build.

Some Brazilians fear this incident may be used by USA's George W. Bush to make a war against Brazil, as happened on Iraq.
