Whakakiia te rerenga e whai ake nei: I te whakahe, i haere tonu a MacDonald i tana kaupapa here ki te whakaatu i te Rōpū Mahi hei kaha totika. I roto i te
General Strike of 1926 i whakahe te rōpū ki te patu whānui, e tautohe ana ko te huarahi pai ki te whakatutuki i nga whakahoutanga hapori na roto i te pouaka pooti. I wehi hoki nga kaiarahi i te mana o te Communist i whakahaeretia mai i Moscow. He kaupapa motuhake, he kaupapa here a waho o te roopu i runga i te pacifism. I whakapono ōna kaiārahi kāore e taea te rangimārie nā te pūmatua, te rangimārie huna, me te tauhokohoko patu. Koia nei ngā take rawa i whakahāwea e kore e aro ki ngā mahara ā-hinengaro o te Pakanga Nui, me ngā taumahatanga ā-hinengaro nui e pā ana ki te iwi me ngā rohe o ngā whenua.
