Sen. Rand Paul, R-Ky., sounded a familiar anti-war note during a Wednesday hearing of the Senate Foreign Relations Committee on the confirmation of Samantha Powers - President Obama's nominee for U.S. Ambassador to the United Nations.

During the hearing, Paul explained that he was concerned by the multiple U.S. military interventions around the world - specifically in Syria.

"The vast majority of the public is not in favor of arming Islamic rebels who in all likelihood with be killing Christians in Syria, the vast majority of the public is not going to be in favor of giving arms to people who are basically aligned with Al Queda in Syria," Paul said.

Paul challenged the Obama administration's decision to arm rebels in Syria, reminding Powers that the executive branch should not be fighting "secret wars" without permission from Congress.

Paul added that it was important to remember that American military forces should not be used as a force to eradicate human rights abuses because war is a "messy business."

"These aren't geo-political games, and they aren't things that we can say, 'Oh we're going to make the world, you know, this great groovy place where nobody has any human rights abuses, but we're going to do it through war,'" Paul explained, expressing concern over "unintended consequences" of United States getting involved in foreign entanglements like Syria.
