Actions are held to be good or bad, not on their own merits, but according to who does them. There is almost no kind of outrage-torture, imprisonment without trial, assassination, the bombing of civilians-which does not change its moral color when it is committed by 'our' side. The nationalist not only does not disapprove of atrocities committed by his own side, he has a remarkable capacity for not even hearing about them.
Like a great poet, nature produces the greatest results with the simplest means. There are simply a sun, flowers, water, and love.
