(This is a recurrent fantasy of mine) I think we should have an independent armed forces with the power to intervene in gross violations of human rights, something like the UN but with exponentially more authority (current UN peace keeping forces are a joke, e.g. see Srebrenica massacre, http://en.wikipedia.org/wiki/Srebrenica_massacre , for just one example of many). This force would have the initiative to wage war…
It sounds good until you explore the details. At the end of the day, someone pays the bills, and whomever controls the checkbook tends to set the agenda. There is no such thing as independence. Flashback to 1985. The Soviet puppet government was committing all sorts of atrocities against people in Afghanistan. Clearly the moral imperative was to stand up for the "freedom fighters", right?
One problem with this would be the "saving fish from drowning" syndrome, e.g. intervening certain acts where the "victims" are all too willing. An example is France's draconian recent law (which I totally back) against burqas: evidently these women are doing this willingly (http://www.guardian.co.uk/world/2011/apr/10/france-burqa-law...), so how can our force intervene?
The more you think about it, the more you realize that, although the current situation is unacceptable and despicable, there are no clear alternatives to it. This is indeed a sad thought.
