Any entity, whether it be a country, a business, a boy scout troop, is made up of the people in it, which reflects their values, culture, history, and the management/government they have.
A true leader is one who is at times self-reflective so that they can see whatever faults they possess that might be the cause of the problems of the people they lead.
To point fingers and blame others is the easiest and least effective way of solving any problem and of leading the people in their care.
A leader “so full of themselves” as my grandmother would say is in fact doing more harm than good for a business, a nation, a religion, a community, an institution, any group of people they are chosen to lead. One needs to look inside first before looking outside because all problems tend to have their roots within.
History tells us that. Our current world situation reaffirms it.
