Can someone give me an unbiased reason for getting involved with libya?

Please don't get all snippy about how much you hate the president... i don't care and you'll only be waisting your time.

Bush (republican) invaded Iraq for false reasons... Now with Obama (democrat) in charge, we're getting involved with Libya for "humanitarian reasons." Both countries had conflict before we got involved, but neither countries were an actual threat to the US. There are plenty of other countries with crazy rulers/dictators in the world that we just seem to ignore. So, what i'm getting from this pattern is that if a country is not sitting on top of a ton of oil, the US could really care less.. Am i right or am i missing something. I understand that the US needs oil, but i wish our government would just be straight up with us rather than making up stories and special missions with out saying "oh and they have a ton of oil and that's truly our main interest." At first, i blamed the republican agenda, but now that Obama's in office and we're still sending our military to places that aren't a threat to us, i'm starting to see that its not a democratic agenda or a republican agenda... It seems to just be America's agenda. Agree? Disagree?
