And to the middle east this even, where that truce between israel and hamas is holding. And this evening, a closer look at israel's iron dome. That some now believe saved lives on both sides of this conflict. Abc's matt gutman is in the region again tonight. Reporter: In gaza, they began scraping away the damage. A massive cleanup, coupled with jubilation. In israel, reservists began packing up and heading home. And streets deserted, all week long, are coming back to life. The rockets and the sirens that sent 3-year-old karin scampering to safety here now quiet. For eight days, three generations of this family huddled in their bomb shelter. Afraid to step outside. Tonight, karin smiling again. And her grandmother, jillian, able to take a walk. What is it like to be able to walk out on the street again for the first time in more than a week. It's wonderful. Bum we're not terribly hopeful. Reporter: They still expect the days ahead to bring more rockets, but they say they feel more protected than before. Now with the iron dome, really, you know, probably the chances of getting hit are smaller than the chance of us wink the lottery. Reporter: The iron dome, a missile defense system developed jointly with the u.S., Which intercepts incoming rockets, with a mind boggling 85% kill rate. This major says hundreds of lives were saved. This is the very first second where this rocket is going to land. And I'm not talking about the whole city, but the neighborhood, a few blocks. Reporter: The system's radar detects a rocket launch and calculates its traject little within a single second. This is a defensive weapon system that has prevented a conflict from continuing. This is really unprecedented in modern history. Reporter: It's been 24 hours since that battery we visited has fired a missile and folks are trying to take advantage of their first opportunity in a week to get outside. But many of them say they don't care to hope for peace, only a sense of quite.
