Trump is shallow, delusional
You are so right as Trump supported the invasion of Iraq on the Howard Stern show...then he didn’t.
He said he would deport 11 million illegal immigrants ...then he said he wouldn’t.
He said North Korea and other such countries should be allowed to have their own nuclear arsenals...then he said he didn’t.
You are right that for Trump ignorance is bliss and if he digs deep into the truth of what he has said in his own words then he would find how shallow and delusional he is.
