SEOUL           -           The South Korean and U.S. militaries announced Thursday that they were postponing their annual joint drills due to concern about a viral outbreak that has infected soldiers in both countries’ armed forces, put many troops in quarantine and closed base facilities. Twenty-two South Korean soldiers and one American service member in South Korea have tested positive for the new coronavirus, which has infected about 1,770 people in the Asian country, the largest outbreak outside mainland China. The allies have previously suspended or scaled back their regular military exercises, but that was part of diplomatic efforts to disarm North Korea, which views the training as a rehearsal for an invasion. It’s the first time that the allies have put off their drills due to concerns about an infectious disease, according to the South Korean Defense Ministry.
