"fighting for human rights and democracy" is a good idea. However human rights and democracy had nothing to do with WW1.  WW1 was another European family fight.

My father came to Canada from Scotland in 1910, joined the Canadian army in 1914 along with 3 brothers, and fought for Britain until 1918. I suspect that is the pattern for many soldiers in the Canadian Army. They were brought up in the Empire. Not surprising that they fought for Britain. 

WW2 we "2nd generations" fought for Europe. 

Korea and Afghanistan, Libya and Syria our military fought for the US. 

Canada was built by all the people who have lived here.
