This legislation establishes a grant program, to be administered by the Secretary of Defense in coordination with the Secretaries of Veterans Affairs and State, for increasing cooperation on post-traumatic stress disorder (PTSD) research between the United States and Israel. The program will award grants to eligible U.S. academic institutions and nonprofit entities to conduct joint research projects with Israeli partners. These projects must address specific PTSD research requirements deemed appropriate by the Secretary of Defense. The bill highlights the significant prevalence of PTSD among U.S. veterans and the general population, noting its links to homelessness and substance abuse. It also recognizes that Israel faces similar challenges with its veterans and possesses substantial expertise in PTSD research and treatment. The Secretary is authorized to accept gifts for the program and must submit reports to Congress on the success of funded research projects. The authority to award grants under this program will terminate seven years after the first grant is awarded.
