Politics: Buddhism in Politics

From Thich Nhat Hanh’s book, “Old Path White Clouds“, a compilation of stories from the life of the Buddha (slightly abridged):

[The Buddha is visiting his father, King Suddhodana of the Sakyas]

The Buddha wished to return to Bamboo Forest in time for the rainy season retreat, as he had promised King Bimbisara and the bhikkhus [monks] who had remained there. King Suddhodana invited the Buddha for a last meal before his departure and asked him to give a discourse on the Dharma for the royal family and all members of the Sakya clan.

The Buddha used this occasion to speak about applying the Way [read the Dharma, the teachings, the truth] to political life. He said the Way could illuminate the realm of politics, assisting those involved in governing the kingdom to bring about social equality and justice. He said, “If you practice the Way, you will increase your understanding and compassion and better serve the people. You will find ways to bring about peace and happiness without depending on violence at all. You do not need to kill, torture, or imprison people, or confiscate property. This is not an impossible ideal, but something which can be actually realized.

It takes a pretty forgiving and positive outlook on human nature to agree with such optimism. Is the Buddha’s message here dated? Can contemporary Buddhists revive the idea (ideal) of such political leadership? Are there any openly Buddhist politicians in the US? What might a Buddhism-based political platform look like? Would Asian and European-descended (and others) Buddhists even be able to agree on such a thing?
