Is Trump a Threat to National Security?

Former President Trump commented on his social media platform yesterday about the Biden administration's decisions to send tanks to Ukraine. He wrote in one post, first come the tanks, then come the nukes. Get this crazy war ended now. Sounds so much like Vladimir Putin. And also I remember he asked a lot of questions really early on about using nukes and whether or not he could use them. In a later post, he wrote in all caps: If I were President, the Russia-Ukraine war would never have happened. But even now, if President, I would be able to negotiate an end to this horrible and rapidly. You know what? Somebody's reporting that he's losing his grip
