A harder US line? Potential Pentagon chief floated idea to sink China fleet in 72 hours
- Michele Flournoy, who is reportedly in the running for the top US defence job, suggested in June that a stronger American deterrence in the South China Sea might make the Chinese military think twice
- But her proposal might be difficult to achieve as it involves a huge reallocation of resources, observers say

In an article in the journal Foreign Affairs in June, Flournoy said that as Washington’s ability and resolve to counter Beijing’s military assertiveness in the region declined, the US needed a solid deterrence to reduce the risk of “miscalculation” by China’s leadership.
“For example, if the US military had the capability to credibly threaten to sink all of China’s military vessels, submarines, and merchant ships in the South China Sea within 72 hours, Chinese leaders might think twice before, say, launching a blockade or invasion of Taiwan; they would have to wonder whether it was worth putting their entire fleet at risk,” Flournoy said.
Defence and diplomatic observers said that realising that idea would come at huge cost but appointing its advocate would signal that the US would keep piling military pressure on China.
Collin Koh, a research fellow from the S. Rajaratnam School of International Studies at Singapore’s Nanyang Technological University, said one point was certain no matter who took office.
