The greatest threat facing the nation at present is not China, Russia, or Iran, but a lack of leadership at top levels, said retired U.S. Army Gen. Keith Kellogg.
Kellogg was named acting national security adviser after the resignation of Gen. Michael Flynn in February 2017. In 2018, then-Vice President Mike Pence chose Kellogg to serve as his national security adviser, while Kellogg continued to serve as an assistant to then-President Donald Trump.
