Certainly, there is the possibility that politics can become unstable through changing leader with every election. Even if it is thought that a strong leader is necessary to win an election, democracy should require citizens of various positions to cooperate. In this modern networked world one strong personality should not simply be ruling but we should be looking to make decisions as a community and rely on strength in numbers rather than the strength of one. Thus, strong leadership like a dictator should not be necessary.
Conversely, since many countries try to maximise their own benefits in international relations, there is a possibility that they will lose pace in international politics if they are not in possession of strong leaders. However there are different types of strength when it comes to leading a country, and at times compassion and flexibility make you stronger as a political candidate than strength of character and outspokenness. Therefore, strong leaders are often required in external matters, but strength may mean that cooperative qualities are sometimes required.
Strong leaders are usually thought to exhibit more ‘masculine’ styles of leadership, being assertive, ego-driven, dominant, competitive and even arrogant or stubborn. However in the age of the internet we are seeing a divided world that seems to suffer a real deficit of compassion, collaboration and togetherness. So arguably a modern leader needs some flexibility, emotional intuitiveness and consensus building abilities to balance out what is commonly perceived as making a 'powerful leader'. Just as society's conception of gender is changing in recent years maybe leadership needs a similar concept change, maybe what the world needs now are more ‘feminine’, caring, and supportive characters in leadership roles.
Angela Merkel may be a good example of this, often being depicted as a strong mother figure for Germans (often fondly referred to as "Mutti" in Germany) and as default leader of the European Union. Merkel has become the longest-serving head of government in the history of the EU by combining powerful economic management, a talent for building consensus, and compassion to deal with some of the biggest problems that have face not only her country but the continent in the last few decades, the global financial crisis and the migrant crisis. Despite controversial decisions and a dip in approval rating following crises, Merkel has undoubtedly overseen a difficult period and led her country to greater economic and diplomatic success, a style that could arguably be wise to emulate elsewhere.
