Because of his pacifist conviction, in the atmosphere of the tense 1930s, he was deemed as guilty of high treason, and the Lapua Movement harassed him relentlessly.
In 1930, an international petition on his behalf was sent to the Finnish defense minister Juho Niukkanen, which included the signatures of sixty British MPs and notables such as Albert Einstein, Henri Barbusse and H. G. Wells.
At the onset of the Continuation War in autumn 1941, he was sent to the front, with orders to make sure he did wear the uniform, and bear and use a weapon.
He remained effectively forgotten for over fifty years, until the publication in 1998 of the book Courage: The life and execution of Arndt Pekurinen by Erno Paasilinna.
[2] According to the book by Paasilinna, Pekurinen's motto was inspired by Jonathan Swift: "As people are not eaten, butchering them is of no use."
