Allison Kaplan Sommer in Ha'arets on transgender soldiers:

'When Ofer Erez heard the Trump administration’s reasons why transgender people were unfit to serve in the U.S. military, each of them contradicted everything he learned in his six years as a transgender soldier and officer in the Israel Defense Forces and as a consultant to the army on integrating transgender troops.
To really understand Israel and the Middle East - subscribe to Haaretz “It’s clearly a decision based on either Trump’s prejudice and transphobia – or on his narrow political considerations. Because it has absolutely nothing to do with military and the quality of service. You can see that by looking at the IDF,” Erez said in an interview with Haaretz. “I feel very frustrated by the situation in the United States because it is hurting good people on the ground doing the work that needs to be done to defend their country.” Two months ago, Erez capped off a six-year stint in the IDF where he served as a commander in the General Staff’s planning division, handling complex national infrastructure projects and commanding hundreds of soldiers. During his service, he helped the army develop policies for transgender service and toured internationally, telling the world his story, under the pseudonym “Captain Shachar” to shield his identity for security reasons.
Today, as a civilian, Erez is the newly appointed executive director of Jerusalem Open House For Pride and Tolerance, the Israeli capital’s hub for services and education serving the LGBT population, both Israeli and Palestinian – and is able to speak freely in his own name, not only as an army representative.'

'In unveiling the new policy, Trump claimed it was “developed through extensive study by senior uniformed and civilian leaders” who, he said, had “concluded that the accession or retention of individuals with a history or diagnosis of gender dysphoria – those who may require substantial medical treatment, including through medical drugs or surgery – presents considerable risk to military effectiveness and lethality.” The truth, Erez said, is precisely the opposite: Transgender soldiers make an army more effective, not less so.
“There are no better experts and no better laboratory than what we have in the IDF," he told Haaretz. "And there, as in any organization, we’ve found that the more diverse an army becomes, the better it functions and the more effective it is. In Israel, our most elite units actively look for people who think differently and live out of the usual framework, who have different abilities and different life experiences.”'

Another example that POTUS weakens his country. America first means in reality America last, or let's say, a very small group of Americans first.
