Once you get out of high school, you should have a chance to read some real history. You might start with Gallipoli. Or Crete. Or Dieppe.
Prove your point that Britain deliberately used Commonwealth troops when high levels of casualties were expected. Simply listing battles where Commonwealth troops did a lot (or most) of the fighting doesn't prove your point. High levels of casualties were expected on D-Day, but Britain contributed troops to take 2 of the 5 beaches, and more troops for the Canadian beach. Plus a paratroop division. Same for Market Garden.
And more British soldiers died in the Gallipoli campaign than ANZAC troops.
Save your cheap smears.
