In all this, the president accentuated the positive, relying on the new Iraqi prime minister, himself a Shiite like departed Nouri al-Maliki, to produce a government around which a majority of Iraqis will eventually rally. Mr. Obama professed to see "some progress, I wouldn't say great, yet." He said Mr. Abadi's "instincts are right," but "whether he can pull it off is something that is going to be a great challenge, and we've got to give him the support we can in the process." Challenged byMr. Kroft that the new government has yet to stir enthusiasm among the restive Sunni majority, Mr. Obama said, "It's going to take time."
