Where Shoud The Focus Be?

After listening to a Forum on KQED I find myself struggling with a notion. In the radio show, they were talking about the continued injustice in the Democratic Republic of Congo. The participants felt that we should be pushing for our country to take a bigger diplomatic stance on this subject. Don't get me wrong here, I'm not saying it's not important. I just think there are a lot of injustices happening right here in this country. How can we continually focus outside our borders to right wrongs while we ignore the wrongs right here at home. It seems like there is only so much energy for good cause out there. Wouldn't it be better to focus inward first? Then once we have our house in order push out to help other people. I've always been a believer in leading by example not by force.
