US presence in Libya?

Do you think we should be in Libya? Why or why not? I personally think we shouldn't, simply because we should let them handle their own business. The more we continue to get involved in other countries affairs, the more our own people will continue to suffer. It seems we're so focused on helping these other countries and their people, yet we can't even help our own people here at home. People are suffering here in the US because of the economy, and very little is being done about it. We should focus more on creating jobs here at home, and stabilizing the economy for our future generations. We spend billions of dollars fixing up other countries and making their people satisfied, but yet we can't help the people who are suffering here. If anything, shouldn't we be 100% fully focused on the disaster in Japan, instead of fighting a war in Libya? Japan needs the most help more than any other country now.
