There are many reasons I oppose a Western military intervention in Libya: the bitter experience of Iraq; the importance of these Arab liberation movements being homegrown; the ease of going in and difficulty of getting out; the accusations of Western pursuit of oil that will poison the terrain; the fact that two Western wars in Muslim countries are enough.
But the deepest reason is the moral bankruptcy of the West with respect to the Arab world. Arabs have no need of U.S. or European soldiers as they seek the freedom that America and the European Union were content to deny them. Qaddafi can be undermined without Western military intervention. He cannot prevail: Some officer will eventually make that plain.
