What were the causes of decline in the british empire?

First: Rapid increase of divorce, with the undermining of the sanctity of the home, which is the basis of society.
Second: Higher and higher taxes; the spending of money for bread and celebrations.
Third: The mad craze for pleasure, sports becoming every year more exciting and more brutal.
Fourth: The building of gigantic armaments, when the real enemy was within; the decadence of the people.
Fifth: The decay of religion; faith fading into mere form, losing touch with life, and becoming impotent to guide it.

Why do you have to ask such hard questions.
