It’s not Morrissey’s view, it’s society’s or the educational/governments viewpoint.
“Call me brave, call me a peace-making hero
Call me anything except what I am
From a class without, I haven't a clue
What the war is about
I haven't got a clue, have you?
Oh no, no, no, no”
singles out, because that is the subject he’s singing about, but he does state that everyone, not just the ‘have nots’ are clueless about war in the last lines of the above section, so he’s not really singling out any particular class.
It’s also the view of the military, people are trained to kill they are programmed to dehumanize other human beings, and likewise the military dehumanizes it’s own soldiers, they are no longer human beings they are weapons to be used.
Cruel subjects need crueler words to describe it. Morrissey seems to be done with sugar coating these days.
It’s not the first time in music, through song. It’s still a brave viewpoint and it’s true.
“And he's fighting for democracy, he's fighting for the reds
He says it's for the peace of all
He's the one who must decide who's to live and who's to die
And he never sees the writing on the wall
But without him how would Hitler have condemned him at Dachau
Without him Caesar would've stood alone
He's the one who gives his body as the weapon of the war
And without him, all this killing can't go on
He's the universal soldier and he really is to blame
His orders come from far away no more
They come from him and you and me
And brothers, can't you see
This is not the way we put an end to war?”
Again, It seems a conscious choice on his part to move away from the poetic style that he once was known for, and it seems over the years he’s been doing this, a way to distance himself from that person he may no longer feel he really is, more or less.
