[quote="Kiburi"]Why doesn't Europe do something for once?

Because modern day Europe has no interest in meddling in the affairs of others.
[quote="Kiburi"]Why is it assumed that the United States are the international police force, or something?[/quote]
Why is it assumed that anything should be done at all? Besides, I don't know who assumes that, but certainly not the rest of the world. Nobody asked you to go to war at any given point.
I agree with the rest of your post, except this:
[quote="Kiburi"]I'm tired of the USA doing everything for everyone else, with our troops, and our tax dollars.[/quote]
Doing everything? For everyone else? Nobody asked you to go to Serbia. Nobody asked you to go to Iraq. Nobody asked you to go to Libya. Nobody asks you to go to Syria, and nobody will ever ask you to go to Iran.
And on the last part I agree again. Would be way better to use those wasted dollars for healthcare, jobs or education.
