Understanding languages and other cultures builds bridges. It is the fastest way to bring the world closer together and to Truth. Through understanding, people will be able to see their similarities before differences.
Choose a leader who will invest in building bridges, not walls. Books, not weapons. Morality, not corruption. Intellectualism and wisdom, not ignorance.
Pick a leader who will make their citizens proud. One who will stir the hearts of the people, so that the sons and daughters of a given nation strive to emulate their leader's greatness. Only then will a nation be truly great, when a leader inspires and produces citizens worthy of becoming future leaders, honorable decision makers and peacemakers. And in these times, a great leader must be extremely brave. Their leadership must be steered only by their conscience, not a bribe.
It used to be said "Build it and they will come," now it is "Build it and bribe them in".
