After a decade, UN chief disappointed in many world leaders

UN Secretary-General Ban Ki-moon says he's disappointed by many world leaders who care more about retaining power than improving the lives of their people — and can't understand why Syria is being held hostage to "the destiny" of one man, President Bashar Assad.

Nearing the end of his 10 years at the helm of the United Nations, Ban spoke frankly about the state of the world and his successes, failures and frustrations as UN chief.
