What is the meaning of "Prove his mantle" in the following sentence?
"Since being elected, Mr Obama has yet to set out his policy towards North Korea. It's time he proved his mantle by releasing one."
Thank you for telling.
'mantle' refers 'to an important role or responsibility that passes from one person to another' - the usual collocation in this instance would be something like, "Obama has assumed the mantle of President."
The USA needs a policy with regard to North Korea. The reporter calls for Mr. Obama to make the policy of the USA very clear to North Korea and the rest of the world - a Presidential act - and so prove that he indeed is worthy of having assumed the mantle of President of the United States.
