The global focus on protecting the United States may be shifting.  One of the biggest threats to American safety may not be coming from Iraq or Afghanistan any more, but from Africa.

FOX News Radio's Jill Nado reports from Washington in our ongoing series on national security:

Securing America.

Gen. Carter Ham is in charge of U.S-Africa Command.  He's warning extremist groups like al-Qaeda, al-Shabaab and others are teaming up on things like terrorist training camps and weapons acquisition in Africa.  He calls it:

(Gen. Ham) "Collaboration and synchronization amongst the various violent extremist organizations, which I think pose the greatest threat to regional stability, more broadly across Africa, certainly into Europe and to the United States."

Ham wants to fight back by strengthening ties between the U.S. and the governments of some African nations.
