NHK reported that the U.S. Navy disclosed that the USS Abraham Lincoln is conducting joint military exercises with the MSDF in the Sea of Japan. The network said the training is aimed at warning North Korea amid speculation that it may conduct a nuclear test or launch a ballistic missile. The network said it confirmed from a helicopter that the Abraham Lincoln was transiting the Tsushima Strait toward the east on Monday afternoon. This is reportedly the first time for a U.S. Navy flattop to be deployed to the Sea of Japan since November 2017 when North Korea conducted repeated nuclear tests and ICBM launches.
