He's incredibly smart. His speeches, policies, his governance reflect his 180+ IQ. But with this superlatives he possesses, he's too busy to flaunt it. Too busy defending his country from quarrelsome neighbors. Too keen to work around his actions in putting his country in safer and better position than adhering to the interfering one-size-fits-all peace negotiation talks from UN. He understands what entails negotiating peace deal means. In a strict sense, he expends significant political capital and energy ensuring that peace and security for his people and his country get it. To negotiate peace, it's important that even though he knows that peace is politically unsustainable, he insists the other side of the deal that they must recognize his and his people's existence. If they fail to acknowledge that simple demand by this smart leader, then, they will miss out on the privileges of a social and political harmony. Anyway, this leader acts and governs his nation. Whether or not he needs to prove his IQ of 180+, he is a good, moral leader who loves his country, and whom his country with its people support and put their trust in.
