Answer:
avoiding further expansion of communist by domino effect
Explanation:
As the domino theory pointed out, American officials and goverment assesment saw that China was already a communist regime , and fearing that South Vietnam would be taken by the North they started sending money supplies and eventually American ground and airforces to fight back the Vietnamese.
The advise was not well based, since the Vietkongs turned to resist the foreign oprresion and then gradually expelled them.
The war effort turned to be a pain for many Americans who saw fighting overseas more like another political movement by the US and the public opinion as a whole was putting pressure in order to send back the veterans.
The international community also saw the Vietnam war much like the Soviet essay on Afganishtan.
