The weak believe that if one has power then no longer will one be weak.  

Why does one feel weak?  

When there is lacking.  

Lacking in self-esteem or confidence, competence or skills and talent, honor or good character, basically attributes that make one feel wholesome and balanced.  

The only time when power is to be feared is when there is abuse of power. 

Any individual can abuse one's power by becoming a bully, an abuser or more extreme, a terrorist.  

A leader can abuse one's power by malfeasance in office.

A government can abuse through corruption and misuse of the people's trust.  

Any strong person understands that true power comes from inner strength of self-esteem, confidence and competence in one's talents.

Any strong leader understands that true power comes from knowledge and the wise application of said knowledge.

Any strong government understands that true power lies with the people, because when the people are prosperous and happy, then the government is stable and secure.

Guns do not make the man as weapons do not make the government.  

What is forgotten when tripping on power or abuse of power?

Any power tripping construct, no matter how powerful, will eventually not be sustainable, because it will be lacking; 

And it would not know what is lacking, because the abuser of power will have lost all sensitivity to people and humanity (in its failure to apply knowledge in a meaningful and wise way for the people).

When empathy and sensitivity is lost, so will wisdom and the knowledge of learning and being attuned to the people.

When knowledge and wisdom is lost, so will the power be lost.
