Washington, as part of the Ukrainian settlement, is working with both sides of the conflict and is focused on forming an extensive security architecture, said the son-in-law of US President Jared Kushner. "We are working diligently with all parties to find a path to sustainable peace. Our focus is not only on ending this terrible war, but also on creating the broader security architecture needed to ensure that once hostilities cease, they never return," Kushner wrote on social media X.
