"It was a sacrifice that was for naught": Veterans and Gold Star families react to fall of Afghanistan

Over the last two decades, more than 750,000 American service members have been deployed to Afghanistan. Amid the chaos in the country as the U.S. pulls out, many are wondering if their sacrifices were wasted. 

"I'm on the verge of breaking down crying because this is just like we gave so much and just like that it's wiped out," said Juan Dominguez, who was a Marine lance corporal when he was sent to the Taliban heartland of Helmand Province in 2010.  It was there that his battalion lost 25 men. Dominguez, who lost both legs and an arm, said his thoughts are with the Afghans who helped the Marines and are now at the mercy of the Taliban.
