Insecure communications, indeed.
"President Trump has been criticized for using insecure communications..."
Most of his tweets reveal deep insecurity, all right. ;)
Trump's got daddy issues, IMHO -- Daddy Fred always told Donny that he had to be the best, do anything and everything to stay on top. But Donny couldn't let himself be as good as Daddy, because Daddy was the best possible. It would be a betrayal if anybody was better. So Trump had to fail, at least enough to avoid betraying the Daddy that dominated him. Bad decisions on casinos, Trump Airlines, various loser golf courses, etc. He always had to go back to Daddy for money, and when Daddy died he (and his siblings) looted Daddy's deep pockets one last time.
Trump is hypersensitive to being wrong because Daddy said he has to be the best -- always right -- but his subconscious knows he's not the best. He's screwed up quite a lot, and he is forced by his inner baby to keep screwing up. Otherwise he would have to betray Daddy by being better.
And this nugget of freshman psychology, fresh off the bullcrap line, is brought to you by an aging USian with fewer synapses than a squirrel. Take it as an elaborate joke. Which it is.
