The Trump Administration Accidentally Texted Me Its War Plans
U.S. national-security leaders included me in a group chat about upcoming military strikes in Yemen. I didn’t think it could be real. Then the bombs started falling.

The aforementioned group chat was using Signal. I guess that is quite the ringing endorsement of Signal's security and trustworthiness.
Signal was already being targeted by every nation-state and major criminal hacking group, I doubt that the knowledge it is being used for US war planning will especially increase the pressure they are under. As a family, we use Signal to coordinate everything important to us.
