In Nixon's time, the cold war took precedence. Iraq was then, and would be under the Nixon's administration, basically ignored.
US President Nixon based his incursion into Cambodia without consulting Congress by the US Constitution's grant of substantive authority which had enabled Presidents throughout US history to send troops into conflicts on their own initiative.
Richard M. Nixon is not responsible for bringing troops home because he continued to escalate the Vietnam War through the secret bombing campaign in Cambodia and Laos. The withdrawal of American troops from Vietnam was later negotiated by Nixon's successor, President Gerald Ford.
Nixon ordered US troops into Cambodia on 01 May 1970; the men were told that it would be a 60 day operation, and that they had to be out of Cambodia when those 60 days were up. The following year in '71, US forces couldn't go into Laos; they had to work the border only. The ARVN went in though (and paid for it heavily).
