[5] In 1924 he was elected to the House of Assembly as MP for Beaufort West, and the following year became South Africa's first Trade Commissioner in the United States and Canada.

Louw was in close contact with Stefanus Gie, the very pro-Nazi South African minister-plenipotentiary in Berlin, who shared his antisemitism.

[9] The memo warned that South Africa was on the verge of receiving a massive number of European Jews, which the document stated were of "...a type in question that does not inspire confidence.

Can South Africa without detriment and even danger to its national interests continue to allow its commerce and related vocations to be fed by recruits of this type from overseas?

[12] Bohle wrote with disgust that Louw had written to Hertzog asking to be reappointed to his post as "minister in Paris" in case he lost the election.

[12] In a 1939 speech in Parliament, Louw stated about the Danzig crisis: "I am convinced that if it were possible to remove Jewish influence and pressure from the press and from the news agencies, the international outlook would be considerably brighter than it is today.

[14] In a 1940 speech in Beaufort West, Louw stated: "The establishment of the OB will contribute especially to the co-ordination of Afrikanerdom's fighting forces.

[15] In another speech in 1940, Louw called for South Africa to become a republic, saying: "Without a doubt radical changes will take part in the political as well as the economic and social spheres.

[16] In 1945, when a Johannesburg Jewish group stated it was willing to pay the costs to send a delegation of South African MPs to inspect the newly liberated concentration camps of Buchenwald and Dachau, Louw was vehemently opposed to such a tour.

[17] Louw suggested that the newsreels and photographs of starving concentration camp survivors were "fake" propaganda designed to discredit Nazi Germany, making such a tour unnecessary in his viewpoint.

[18] In early 1948, Louw wrote a pamphlet for the National Party entitled Die Kommunistiese Gevaar in Afrikaans and The Communist Danger in English for the coming elections of that year.

[19] Louw wrote that Smuts was content to "let things develop" instead of banning the South African Communist Party as he wanted.

[19] Louw ended his pamphlet with the call for all South African whites, whatever they be Afrikaners or Anglos, to vote for the National Party.

[20] Through Louw could be charming when he wanted to be, he was well known as a combative man with an explosive temper who was widely disliked within the South African diplomatic corps.

[21] Louw also hired six Madison Avenue advertising agencies to run ad campaigns depicting South Africa as a benevolent society whose apartheid system worked for the mutual benefit of both blacks and whites.

[26] Through Nkrumah was an icon of Pan-African nationalism and of Black pride, he agreed with Louw that the Commonwealth conference was an "inappropriate" venue for discussing apartheid.

[29] Louw had a major impact on Canadian relations when he met with the Prime Minister of Canada John Diefenbaker at the 1957 and 1958 Commonwealth conferences.

On 30 October 1958, the American delegation at the United Nations for first time ever voted for a general assembly resolution condemning apartheid.

At the 1961 session of the United Nations, Louw represented South Africa when he became involved in stormy debates with the Indian delegation who objected to the treatment of the Indo-South African population under apartheid.

[34] His thesis was summed by Time as: "South Africa's rigidly repressed blacks are actually enjoying blissful freedom and enlightened education".

"[34] Louw depicted the newly independent African nations as falling into the Soviet sphere of influence, saying: "The ruler of Ghana is flirting with Moscow and Peking.

Time magazine in its edition of 20 October 1961 condemned the censure of Louw as "...an alarming display of emotionalism and political immaturity" by "Africa's new nations".

[35] Simha Pratt, the Israeli ambassador to Pretoria, reported "I saw before me panicky people, gripped by fear and without a backbone" as dozens upon dozens of South African Jews arrived at his office to tell him that Israel's vote at the UN had made life very difficult for them and that Israel must not criticise apartheid as Louw was an anti-Semite who always looking for any chance to lash out at the Jewish community.
