Should Western Values Be a Condition of Foreign Aid?

Uganda's President Yoweri Museveni has broad support in Uganda for a new law imposing sentences up to life in prison for homosexual acts. Nigeria and many other sub-Saharan nations also have anti-gay laws. Such harsh anti-gay laws in African countries have the US and other donors threatening to reduce foreign aid. Norway, Denmark and the World Bank have withheld or diverted some $110 million in aid. President Obama says the US is "reviewing ties." Is it right to withhold food and medicine based on acceptance of western values? Will attaching strings to foreign aid make targeted leaders stronger than ever? Will African soldiers continue to protect western interests? Finally, does aid do more harm than good by making nations dependent? Would the money be better spent to help them help themselves?
