Is this the *test* Joe Biden was referring to?

Maybe Joe Biden is having an attack of conscience?

US intelligence: Iran will be able to build first nuclear bomb by February 2009 DEBKAfile Exclusive Report

October 21, 2008, 1:06 PM (GMT+02:00)

US intelligence’s amended estimate, that Iran will be ready to build its first bomb just one month after the next US president is sworn in, is disclosed by DEBKAfile’s Washington sources as having been relayed as a guideline to the Middle East teams of both presidential candidates, Senators John McCain and Barack Obama.

The information prompted the assertion by Democratic vice presidential nominee Joseph Biden in Seattle Sunday, Oct. 19: “It will not be six months before the world tests Barack Obama like they did John Kennedy.”

Can anyone confirm this? If both campaigns were briefed on this, why is the McCain Campaign silent?
