Per the Korean Central News Agency:
"Nobody can deny the entity of the DPRK which rapidly emerged as a strategic state is capable of posing a substantial nuclear threat to the U.S.."
"Although grave challenges that should not be overlooked face us, we neither feel disappointed nor are afraid of them but are optimistic about progress of our revolution under this situation."
Kim's comments were made during his opening speech at the 5th Conference of Chairpersons of Cells of the Workers' Party of Korea (WPK) earlier today.
