Regarding the Iraq war, Gen. Mattis said he thinks the U.S. is on track to meet its self-imposed goal of ending its combat mission by the end of August, despite the lack of a government 4½ months after Iraqis went to the polls.

Gen. Mattis said the “greatest long-term challenge in the region” is Iran, which “continues to threaten regional and global stability by pursuing a nuclear weapons program and by funding, arming, and training militant proxies throughout the region.”
