The last U.S. Marine off the roof of the U.S. Embassy in Saigonsays the Afghanistan mission was too long, and he questions its purpose.

The big picture: Juan JoséValdez's last-minute escape is recalled as Americans watch the images of Afghans rushing toward aircraft at the Kabul airport. The Mexican American master gunnery sergeant told Telemundo Noticias the anguish and despair seen in Afghanistan as the U.S. carries out a chaotic withdrawal is triggering memories of the similar scramble during his last days in Vietnam.

• The former embassy guard said he's worried about the future of women in Afghanistan, as he was about the women in Vietnam.
• Valdez recalled, “They would give us the children, saying 'Please, at least take my children out. I’ll stay if I have to, but take my daughter away.

Details: Thousands of Americans remain in Afghanistan, along with tens of thousands of Afghans awaiting Special Immigrant Visas.

• Multiple news organizations have reported that the Taliban has turned away Afghans, including some with documentation from the U.S., from roads to the airport and even beaten some at checkpoints.

What they're saying: "We spent so much money, so many weapons, and so many infantry and Army deaths, and for what, for what?" Valdez told Telemundo Noticias.

• Valdez told the San Diego Union-Tribune he believed the withdraw in Kabul is worse than the one in Saigon because the fate for the Afghans who worked with the U.S. during two decades of occupation is unknown.

Flashback: Valdez was one of the last 11 U.S. Marines out of Vietnam before the fall of Saigon on April 30,1975, and he was featured in the 2015 PBS American Experience documentary, Last Days in Vietnam.

• In the film, the San Antonio, Texas-born Marine talks about sitting on the roof of the U.S. Embassy with 10 other leathernecks, waiting for a helicopter to rescue them as North Vietnamese forces were about tocapture the city.
• "We were kind of sitting down around ... looking at each other [and] wondering... if they had truly forgotten about us."
• A chopper finally came, and Valdez ordered everyone to board. But as he prepared to jump on, Valdez slipped. The ramp went up as he dangled in midair.
• The Marines pulled Valdez into the chopper at 7:58 a.m. Saigon time, and he officially became the last U.S. Marine to leave.

The state of play: The fact that Valdez's heroics were largely overlooked until recently is another example of the often-overlooked experiences of Latino veterans in U.S. wars. Their contributions to Operation Enduring Freedom during 20 years in Afghanistan are just being recognized by the general public.

• 1st Lt. Jennifer Moreno, a nurse and University of San Francisco graduate, was killed in October 2013 after she tried to save a soldier wounded from a suicide bomber explosion. Last year, a clinic at Joint Base San Antonio Fort Sam Houston was named in her honor.

By the numbers: Hispanics comprise around 16% of all active-duty service members, according to a USA Today analysis of Department of Defense data.

• Nearly 200 Latino enlisted military personnel were killed in Operation Enduring Freedom in Afghanistan from October 2001 to September 2014. That's 8.5% of all casualties, records from the U.S. Defense Casualty Analysis System showed.
• Operation Iraqi Freedom claimed the lives of 467 Latinos in the U.S. military, 10.6% of all casualties in that conflict.
• Officially, Defense Casualty Analysis System says Hispanics only accounted for 349 of the total 58,220 U.S. casualties in Vietnam, but the U.S. Department of Defense did not keepdetailed records on race and ethnicity at the time. Other studies suggest 20% of the causalities were Latino.

What we're watching: The League of United Latin American Citizens (LULAC), the nation's oldest Latino civil rights organization, is pushing for the passage of the Brandon Act.

• The bill would ensure that service members can receive a confidential mental health evaluation referral, without fear of retaliation.
• The proposed legislation is named after 21-year-old Navy aircrew mate Brandon Caserta, who died by suicide in 2018 at Naval Station Norfolk.
