Thanks GSS.
I do not know much about Barry, and so asked you to verify the Wiki statement.
This is from a Sinn Fein site.
Barry would assert in later life that he opposed both the 1930s bombing campaign in England and IRA contacts with Nazi Germany. In fact in January 1937 he had taken a trip to Germany seeking to find out the extent of German infiltration of the IRA. German support was assured to him subject to the condition that the IRA limited its actions to British military installations once war was declared. Financing was to be arranged through Clann na Gael in the USA.
