Retired Lt. Gen. Robert Gard, who’s now a member of the Center for Arms Control and Non-Proliferation’s national advisory board, said military options could mean taking out North Korea’s ability to launch its own strikes.
North Korea has a massive amount of artillery just across the demilitarized zone that could hit Seoul in response to a U.S. strike.
“Given the volatility of the North Koreans, they just might respond in a way that would result in thousands of casualties in South Korea,” Gard said.
