It is a very old saying but it has a lot of meaning. Power does come with responsibility and those who ignored the latter part of this phrase lost their former part too.The British Empire was so successful in its early days because it took care of its subjects and felt responsible for them but as they became stronger,they became more ruthless and began ignoring their responsibilities.
They became self-centered and interested only in their powers.
As a result they were stripped off their powers and now remain only as a shadow of their former selves.
The French and the Russian,who like their British counterparts forgot their responsibilities,were subjected to a much cruel and sudden downfall.Of their once unchallenged power,nothing remains.
Shakespeare was true when he said,”Uneasy lies the head that wears the crown.”Even though the world has changed much,some of the world rulers today are following the footsteps of their older counterparts.It is hoped that they realize their responsibilities and save the world and themselves from a lot of trouble.
