Secretary of State John F. Kerry came to Iraq on Wednesday to congratulate a new Iraq government on which the United States is basing much of its emerging strategy to counter Islamic State militants. Kerry met with new Iraqi Prime Minister Haider al-Abadi and other senior officials. His visit is timed to precede President Obama’s speech Wednesday evening laying out a multi-pronged plan to confront militants who have seized large swaths of Iraqi and Syrian territory with stunning speed and battlefield prowess. Abadi told Kerry that the threat from Islamic State militants is growing. “It’s mobilizing an international network,” drawing funding and foreign fighters to their cause, Abadi said following a meeting with Kerry. “We are fighting these people,” Abadi said. “They are a challenge to the whole region, to the international community.” He appealed for more and immediate international help.
