Somali Pirates

The only effective government Somalia has had since 1991 was the brief tenure of the Islamic Courts Union (ICU, with vague ties to Al-Qaeda). They virtually eradicated piracy (it was punishable by beheading), and imposed Shari'a. But their government was overthrown by American-backed Ethiopian troops. So now the questions arises - do we engage the ICU and try to reposition them in power? Or are piracy and anarchy throughout the country just the price we pay for keeping the ICU out of power? And would people even be mentioning this as a possibility if piracy were not disrupting oil shipping?
