US troops head to Nigeria

The US is deploying 200 soldiers to Nigeria to train troops battling Islamist militants. In October, the White House began warning that Christianity faces what it called an "existential threat" in Nigeria. Amaka Anku, who heads the Africa Practice at Eurasia Group says the reality on the ground is more complex. She tells The World's Host Marco Werman the US military deployment is largely welcome but isn't expected to create stability.
