Right... another spin that they use. Canadians weren't fully (I mean FULLY) engaged until Sicily 1943... two years after the US entered the war unless you count the failed raid at Dieppe in 1942.
By their own Canada at War website... the first Canadian infantryman (Pvt. John Gray) killed was December 13, 1941.
1.) Failed raid means what? Thats like saying American's don't get to count pearl harbour as being involved because it was a giant failure, and claiming they don't get to count being overrun and taken as POW in the pacific either.
2.) You are aware infantry is not the same as armed forces. Are you saying Britain doesn't get to count the Battle of Britain? That the war in the Atlantic or Pacific don't count?
You must certainly believe that Midway's losses didn't count as being involved since no infantrymen died.
Its also unfair though to claim the USA wasn't involved in combat before its official start.
It had volunteer squadrons in China and Britain fighting the Axis, as well as naval escorts long before pearl harbour.
To claim America wasn't involved until Pearl Harbour is like claiming China wasn't involved until then. It wasn't official, but America was helping defeat Japan and Germany long before it was attacked.
