The idea of reform intervention, or toppling a tyrannical regime, is one that has often been a contentious one, and is also very topical thanks to the most recent situation involving Osama Bin Laden (more of a breach of sovereignty than invasion however) and the wars in Afghanistan and Iraq (which was per se veiled more as a pre-emptive attack than a reform intervention, but that has been the aim of it more recently). The issue, from a theoretical standpoint as well as from any other, is a thorny one. It raises many questions regarding the theory of Just War, a nation's right to self determination and sovereignty, amongst others.
