The U.S.

and Iran held talks a week ago.

More talks are expected, but haven't been announced.

The U.S.

already has thousands of troops, dozens of warplanes, and roughly a dozen ships, including another aircraft carrier in the region.

The sides are far apart, and here's the real catch.

In most negotiations, if the two sides can't agree, the diplomats go home and decide whether to meet again.

This scenario is different.

The U.S.

has spent a month moving Navy ships and warplanes into the region.

If there's no deal, President Trump could unleash attacks on Iran.

If you needed to know the population of Kenya, the size of Brazil's economy, or the military budget of China, a go-to source was often the CIA's World Factbook.

It began in 1962 as an internal classified manual.

In the 1970s, the factbook became available to the public as an annual reference work popular among journalists, researchers, and travelers.

In announcing the closure, the CIA noted that some of the photos came from CIA officers operating around the world.

The agency isn't saying why the fact book is coming to an end.

However, CIA Director John Ratcliffe has said he wants the agency to pare back programs not considered part of the core mission.
