>> well, it's because they're doing important work. but also, it's a key city, and those who live there are loyal allies to the u.s. the americans do not want it to fall. because surely isis would try to go after baghdad. >> and now to john karl at the white house. we saw that image in the oval office. what's the feel there tonight? >> reporter: well, some cautious optimism tonight. this may have jolted the iraqi government into getting its act together. some hope we could see a new iraqi prime minister in the next week. this was a decision that the president didn't want to make, but this message is that this is a limited mission. but there will be no mission creep. the objective is narrowly defined. prevent a humanitarian catastrophe on that mountain top. and the president told us, there is simply no u.s. military solution to iraq. it couldn't happen with more than 100,000 troops under president bush, it can't happen now. this is a narrowly-defined mission. >> thanks to you both. and the other breaking story tonight. look at the big screen behind me. that little circle on the screen behind me, the eye of tropical storm iselle tonight. a direct hit on hawaii. and hurricane julio coming up right behind. this was a one-two punch coming. and tonight, the people living there hunkered down, and the trees, power lines down. chaos at the airports. the gas pumps wrapped in plastic. this evening, will all the water trigger landslides?
