Intermediate centrist organizations centered about the London Bureau represent merely “left” appendages of Social Democracy or of the Comintern. They have displayed a complete inability to make head or tail of the political situation and draw revolutionary conclusions from it. Their highest point was the Spanish POUM, which under revolutionary conditions proved completely incapable of following a revolutionary line.
Ang mga intermedyang sentristang organisasyon na naka-sentro sa Kawanihan sa London ang kumakatawan lamang sa “kaliwang” buntot ng Sosyal Demokrasya o ng Comintern. Sila ay nagpapakita ng isang kumpletong kawalan ng abilidad na manguna o bumuntot sa pulitikal na sitwasyon at kumuha ng mga rebolusyonaryong kongklusyon mula rito.
