Can you repeat this sentence, but add in punctuation?
The attack on "kings and princes" was merely "cover" for the true attack, on all nationhood (as time has shown; now that the supply of kings and princes has given out Communism impartially destroys proletarian prime ministers and politicians); and that on "priests" was a disguise for the real attack, on all religion.
