* Assassination can counter-productively rally citizens around a regime. Assassination is likely to be counter-productive, rallying popular feeling around a repressive regime as external enemies or internal minorities are blamed, rightly or wrongly, for the act. This is even more likely to result from an unsuccessful assassination. Furthermore an alternative now exists for bringing dictators to justice. Regime change has been shown to be possible in a number of countries and former dictators are being held to account for their actions. The Special UN Tribunal for Former Yugoslavia has been able to put Slobodan Milosevic on trial, and Saddam Hussein is facing justice in Iraq. The International Criminal Court now provides a permanent forum for such action to be taken, and is itself a deterrent to would-be tyrants in the future.
* To liberalize a regime, there are better ways than assassination. Alternatives such as constructive engagement or economic sanctions are preferable and much more likely to result in eventual liberalisation of the regime, albeit slowly. The examples of Eastern Europe in 1989 and Yugoslavia in 2000 show that even in apparently hopeless cases, change can come through popular action, often quickly and without great violence. Cambodia in 1979, Afghanistan in 2002 and Iraq in 2003 all saw dictatorships quickly overthrown by external forces.
