Whakaotihia te rerenga e whai ake nei: I te tau 1956, i tohua e te Perehitini Dwight D. Eisenhower a Parsons hei Ambassador o te United States ki Laos, te upoko o te US embassy i Vientiane, me Parsons e whakaatu ana i ana korero i te Oketopa 12, 1956. Hei karere ki te Kīngitanga o Laos i waenganui o te
Ko te Pakanga Tangata o Laos, e tohuhia ana a Parsons me te tautoko a te tari Eisenhower mo te Kawanatanga o Royal Lao ki te Pathet Lao. I mutu tana mahi ki Laos i te Hui-tanguru 8, 1958. I haere tonu a Parsons ki te tautoko i te kaupapa here a te tari ki Laos i te tau 1959-61, i taua wa ko ia te Kaiawhina o te Hekeretari o te Kawanatanga mo nga Take o Ahia ki te Rawhiti me te Moana-nui-a-Kiwa. (I whakawhiwhia ia ki te tari i te Hurae 1, 1959, a ka whakarerea e ia te tari i te Maehe 30, 1961.) I a Parsons e whakaatu ana ki te United States Congress i te Poutu-te-rangi 1961, i kii ia "he tino nui te kawenga a te United States i Laos, a ko te tumanako kaore he pohehe mo to maatau pakari me to maatau". I roto i tana pukapuka 1965 "A Thousand Days", i tino whakahe a Arthur M. Schlesinger, Jr. mo te huarahi a te Kawana Parsons ki Laos (i pai a Schlesinger ki te kore o Amerika i waenga i nga rangatira me nga tutu), e kii ana ko Parsons "he tino kino te ahua". Kaore a Parsons i whakautu ki tenei, ki etahi atu whakahe rite ranei.
