The strike group, including the 97,000-ton carrier and its 60-plus aircraft, the guided-missile destroyers USS Wayne E. Meyer and USS Michael Murphy and the guided-missile cruiser USS Lake Champlain, will arrive off the Korean Peninsula by the end of April, multiple United States defense officials told CNN.

"If the U.S.is planning a military attack against us, we will react with a nuclear pre-emptive strike by our own style and method".
"North Korea is the most risky and urgent threat to peace and security in the Asia-Pacific", Mr Pence said.
"Obviously, it's an intimidatory tactic adopted by the Trump administration to push Kim Jong-un to yield to Washington's carrier threats", Li said.
