The only people that read his tweets are his subscribers which is his base who believe in him and cnn who then makes an entire days news off of each tweet.Trump has shown himself to be low information or no information in his tweets. Does that inspire confidence? His dishonesty is unraveling any faith a foreign ally might have in him.
Sorry, I see him as appearing to be unreliable at best.
I cannot comment on your post as I don't read his tweets but tweets are only x amount of characters long so anyone that reads them can read them the way that person wants to read them. They aren't policy, they aren't voted on or signed into law, they are 100% meaningless.
Just a way for his base to get excited and his political opponents to tear him down.
