Giving brainliest and 30 select all that apply: which of the following contributed to the u. s failure in vietnam> a) most people in all parts of vietnam wanted to be free of all foreign influence. b) the united states supported corrupt leaders in vietnam. c) the united states entered the war in order to make vietnam a u. s colony. d) only a few u. s soldiers fought with honor.

Causes of US failure in Vietnam include b) The United States supported corrupt leaders in Vietnam and d) Only a few US soldiers fought with honor. 

One of the biggest issues of the Vietnamese war was that the United States went in because of anti-communism above all other reasons because of the Truman Doctrine. The South Vietnamese leaders were not well liked and were overall corrupt. The knowledge of this back home created a lot of public tension and actually caused soldiers to feel they weren't fighting for a good cause, or even commit war crimes as seen in the My Lai Massacre. 

Hope I could help!
