Perhaps some people need a history lesson. The CCF WERE the NDP in 1940. They basically changed their name to the NDP in the 1960. The CCF were Socialists as are the NDP are today.
Some members of the CCF were against going to War in Europe UNTIL the Soviets were attacked by the Germans.
So Harper is partially correct. The CCF-NDP initally oppose the war. But the general population does not seem to know this fact.
Including the majority of the people on this forum.
It seems like you are also in need of a history lesson.
Canada entered the war in 1939 on a vote where all members of the CCF caucus but JS Woodsworth voted in favour. The CCF National Council voted 13-9 in favour of joining the war. The USSR was not invaded by the Nazis until 1941.
Harper is bringing up this old history to divert attention away from a stupid war that is seemingly never ending and accomplishing nothing.
