Griffin had already possessed personal political unease at the actions of the British Government in initiating the United Kingdom's entry into the conflict before his deployment in theatre, and during three months in the environs of the capital city he became disillusioned with the nature of the work in which he was engaged.
[9] In 2011 Griffin took part in a demonstration outside the American Embassy in London in support of Chelsea Manning, a United States Army soldier who had released a mass of classified military documents to public view via an internet outlet.
[10] In April 2013 Griffin took part in a debate at the Oxford Union supporting the proposition "We will not fight for Queen and Country", during which he stated that patriotism is a "false religion", that was propagated self-servingly by influential elitist groups in society who financially benefited from it.
[11] In March 2015, as a representative of Veterans for Peace, Griffin went to Northern Ireland to meet with ex-paramilitaries from the Provisional Irish Republican Army, including Seanna Breathnach.
The ex-IRA participants expressed in return a new understanding of the "programming" that the Veterans for Peace representatives had explained they had been subjected to in the British Army, but stated they shared no reciprocal regrets about their own activities in the conflict.
