Ignore the yanks and there apparent lack of knowlege. Their war only lasted a few years, not the six in our history

(Expecting incoming)
Besides just remind them that at least it has'nt lasted as long as the dreaded VIETNAM

The official conflict is from '65 to '73 but they had advisors over there as early as '62/'63.
Nooooo!
May 8, 1950, Secretary of State:
"The United States Government, convinced that neither national independence nor democratic evolution exist in any area dominated by Soviet imperialism, considers the situation to be such as to warrant its according economic aid and military equipment to the Associated State of Indochina and to France in order to assist them in restoring stability and permitting these states to pursue their peaceful and democratic development."
That included advisers and training to prop up the French in their war. And then bombers, military advisors and technicians. From 1950 to 1954, authorized US aid amounted to $1.4 billion and constituted 78 percent of the French budget for the war until they got completely pasted at Dienbienphu. (The CIA had helped the French airlift 16,000 men in and delivered supplies throughout the seige)
French are formally defeated and cue loads of dark plots around the Geneva Settlement that ends up in the creation of North and South Vietnam. US starts to get physically involved again in May 1956 sending 350 advisers and technicians to the South. And it all starts to build up towards the 1962 deployments.
So really the US have been involved on and off for 56 years.
(And it is all the fault of the French who kicked it off in 1857 by invading.)
