Saddam Hussein

What with the trial of Saddam Hussein kicking off today, I engaged in a conversation about "what is the right thing to do" with regards to the trial. In the course of this discussion, someone pointed out the basic dilemma for lookers-on such as myself:

I think these issues are genuinely very difficult. I'm strongly opposed to capital punishment under almost all circumstances, but to what extent are we entitled to tell another country how to run its legal system? Particularly given the US's record on capital punishment. This is a classic liberal dilemma - is liberalism a commitment to a positive set of values or a commitment not to impose values?

Time will tell, right?
