Totally agree with you that 'war is a swindle forced on ordinary folks for profit and power of the elites.'  
Darn tootin' it is.
But I wear a poppy in memory of a dearly beloved, now deceased family member who served as a young man because that's just what decent young men did in those days.  The family member that I'm referring to grew up in a remote part of Canada and was relatively naive when called upon to 'serve'.  Just doing what his elders expected of him.
