It is within any nations best interest to secure its own security and prosperity, at home and abroad. American politics, along with decisions it affects, need to utilize cost/benefit analysis more readily as would a business. It is within the nations best interest to make sure that any and every decision it makes regarding foreign affairs benefits itself more than others. Some may say this is "selfish"; to those who do, I would urge them to educate themselves by reading Adam Smith's The Wealth of Nations. Limited resources and unlimited demand is the basis for economics. Having said that, if it can be proven that assisting African nations in building infrastructure to produce more electricity will in turn benefit the US in a positive way, action should be taken. If not, then no action should be taken.
