America must optimize forces to avoid losing a war with China, Air Force Secretary says

Air Force Secretary Frank Kendall warned that the U.S. military may be unprepared for a conflict with China, and "might even lose" a hypothetical war.

"The threat of attack from violent extremist organizations still exists, and we will address those threats as they occur. But China is by far our pacing challenge," Kendall said.

"Our job is to deter that war and to be ready to win if it occurs," Kendall said. "We’re all talking about the fact that the Air and Space Forces must change, or we could fail to prevent and might even lose a war."
