Can the assassination of a dictator be justified?

[ghetosmurph]

The assasination of a dictator is moral if all of the following apply
1) Said dictator is clearly a tyrant
2) There is no lesser means to remove this person from office
3) It must be clear that the death of this person would make a change for the better
4) There must be replacement government lined up to take over

So for example, since we're on the topic of hitler, lets go with the Stauffenberg Conspiracy.

-Was Hitler clearly a tyrant? Yes
-Was there any other way to remove Hitler from office? No
-Would the death of hitler at that point in WWII have made a change for the better? Yes, b/c with Hitler overthrown, a new government could negotiate with the allies to save Germany from harsh punishment (which was the whole basis of the plan in the first place)
-Was there replacement government lined up? Yes, and they even had people to seize all the key positions in Berlin as soon as hitler was killed.

Now, did the plan work? No, and there were a bunch of reasons for that, but it was a morrally justified assasination attempt. Now I would like to point out, when I say moral, I mean this is the official teaching of the Catholic church on the subject, so it a my vary between different religions what is considered moral. Anyhow I would have to go with yes, the assasination of a dictator can be justified.
