"If it was wrong not to protect the consulate in Benghazi, then it's wrong not to protect the consulate in Erbil."

In an interview with Nick Gillespie, Sen. Rand Paul (R-Ky.) explains why he supports limited military action in Iraq:

While the beheadings of U.S. citizens James Foley and Steven Sotloff are a factor, he says, Paul is especially insistent that protecting the U.S. consulate in Erbil, Iraq is a major cause for ongoing concern. Erbil is near Mosul, a city overrun by ISIS with relative ease, he says, and it's of paramount importance that the United States protect its diplomatic personnel in Iraq.

"If it was wrong not to protect the consulate in Benghazi, then it's wrong not to protect the consulate in Erbil," he says.

In the same conversation, Paul also reiterates his commitment to congressional authorization of all warmaking, the need to stay out of Syria, and why Middle Eastern countries must be the ones who bear the biggest burden in defeating ISIS.
