The Holocaust, a genocide and more

Can something be too soon a metaphor
The Holocaust, a genocide no more
A word for something evil  done by man
A little worse than burning the best pan

Do metaphors make people do bad deeds
When we need  new ways and  stunning schemes
How about  we torch the Union Jack
And throw it  at a Constable hay stack

That’s pathetic, we need nuclear bombs
Stored inside the wombs of  virgin nuns
When birth arrives a triumph and a roar
The London Hospital shall be no more

No London,no New York,no Leningrad
Just a beetle  looking quietly sad
