Former national security adviser Robert O'Brien, who is expected to have a prominent role if Donald Trump returns to the White House, has revised his proposal to sever US-China economic ties. Initially, O'Brien suggested sending the entire US Marine Corps to Asia as part of this plan. However, he clarified that only a "fighting force" would be deployed, with some Marines remaining at bases like Camp Pendleton and Camp Lejeune. O'Brien outlined his thoughts in a 5,000-word article submitted to Foreign Affairs.
