you can't let a dictator openly declare murder on thousands of citizens and expect the rest of the world to look the other way Den, unless its in Africa....or they have nukes....or they dont have oil.... 
Yes I do agree BJ and it does little good for that fact but, by extension, the ramifications of interfering in this particular region are subsequently greater than trying to sort the iniquities of the tribal and often incestuous system of 'government' seen in sub-Saharan Africa.
That aside, one could understand the validity of this action if it were based on the morality of concern for oppressed peoples - but we all know that it's nothing more than a jockeying for position, power and influence in the region.
Would the numbers of those subsequently killed in Iraq – where regime change was forced - have been as great had the 'West' not invaded?
In my view the time to act in the region is when a situation has run its course (in terms of regime change) and when the majority of the people are satisfied with the result and actually ask for help to rebuild their country.
However, help should only be considered (on the scale of nation regeneration) if those offering it can actually afford to give it and, by doing so, don’t deny their own people by giving it - but as ever, the peculiar political structure of the region should be uppermost in the minds of those who think that ‘western’ values and ‘democracy’ will be easily applied in a region that has survived under the dictator’s boot or tribal group for so long.
If that means that we and our military power should keep out of it then that's what we should do, because as far as I can see, we have opened yet another can or worms in a region where more military interference by the 'West' is the last thing to be considered.
This action will cost us dearly and will destabilise a part of the region to the extent where the results such interference may well have profound political and strategic consequences for the foreseeable future.
