"ナイジェリアの問題は単純かつ明確に指導者の失敗です"

Simplified Meaning:

Nigeria's main problem is that its leaders have not done a good job running the country. Think of a football team with a bad coach. Even if the players are really good, they won't win games if the coach doesn't train them well, make smart plans, or guide them properly. Nigeria is full of smart and talented people with many resources, like oil and fertile land, but these advantages are wasted if leaders are corrupt or incompetent. When leaders don't make good decisions, it affects everything: schools might not prepare children for the future, hospitals may not care for the sick properly, and roads might be in bad shape, making travel difficult. For the country to improve, it needs leaders who are honest, skilled, and dedicated to serving the people. Following this wisdom, individuals should be careful to choose leaders who truly have the country's best interests at heart and demand accountability from those in power.
