Prying into others affairs for political reasons is a tricky slope. You can end up in Iraq and other unsavory places. However, what tragedies might have been avoided if the world had been a little more involved in Hitler's backyard in the 1930's or in Rawanda not very long ago? If we stuck to the mind your own business school of international policy, imagine what attrocities could be committed, imagine what abuses of human rights.
I would hope, and I know, there are people working all over the world, in their own countries and internationally, to prevent the abuse of women and the trafficing of humans. I damn sure hope they don't limit themselves to their own backyards. Sometimes the spark that lights the fire under a government to do something about a problem comes from international pressure (like, to various degrees, whaling, nuclear safety, the drug and arms trade, human rights, economic reform, etc. etc. etc.)
I would rather be accused of sticking my nose over fences than have to tell a 16 year old tricked into working a sex club in Japan that she is on her own because the country I come from has its own problems - very sorry, can't help you and won't bring your plight to the attention of the world community because we have teens selling their bodies for drugs. Since they come from my country, they are much more important than you. Why don't you enquire next door?"
(my post is not aimed at anyone who posted/will post, rather the general isolationist attitudes that pop up from time to time - please don't take it all personal like).
