Chairman of the Joint Chiefs of Staff General Joe Dunford warned Tuesday that any war with North Korea would be “nasty,” saying America still hopes to find a peaceful solution to the crisis. The Pentagon’s role is to bolster diplomatic efforts by providing a clear message about US warfighting capabilities, AFP quoted the US military’s top officer as saying. “Right now, the military dimension of the problem is reinforcing Secretary [of State Rex] Tillerson’s economic and diplomatic pressure campaign,” Dunford told reporters after he visited US Marines temporarily deployed to an Australian air force base in Darwin. Dunford added the US seeks a peaceful outcome to the crisis over North Korea’s push to develop intercontinental ballistic missiles. However, he said President Donald Trump has asked him and Defense Secretary Jim Mattis for a “full range” of military options.
