Depending on a reader’s thoughts of Donald Trump, one may either grumble “what an idiot” by the end of each page or “what a bunch of BS.”

But Bob Woodward is not known for dealing in BS.

The two-time Pulitzer Prize winner’s books and news coverage have been giving presidents and their administrations headaches and heartaches all the way back to Woodward and Carl Bernstein’s coverage of Richard Nixon and Watergate for The Washington Post.

President Trump is no exception — and he’s not the only who receives tough treatment in Woodward’s latest, “Fear: Trump in the White House.” Presidents Barack Obama and George W. Bush policies also receive some knocks.

But it is Trump who bears the brunt of Woodward’s skills here.

Through “deep background” sources, numerous interviews, deep dives into documents, etc., Woodward always writes like he is a fly on the wall during meetings between presidents and their high-ranking administration officials. He uses the same technique that he has employed with Obama, the Bushes, Bill Clinton, Ronald Reagan, etc., for his coverage of Trump.

Given the heavy media coverage of “Fear” during the past couple of weeks, many people may know the book is a hard look at “Trump in the White House.” And Trump does not look good in that look.

Most of the cabinet members featured in the book refer to Trump as an idiot at some point. Some cabinet members treat him as if he’s a child who has to repeatedly told why he cannot have cookies before dinner. Except rather than warnings about cookies, they have to repeatedly remind the President why he cannot flagrantly disregard or terminate various agreements with allies around the world.

Aides take papers off the President’s desk so he will forget about them.

There are a few people who come across as heroes in the book. People who seem to be able to dial the President back from making world-shattering decisions. They include Defense Secretary James Mattis, Senator Lindsey Graham and Rob Porter, the assistant to the President who stepped down after his ex-wives accused him of domestic abuse.

They developed ways of speaking with Trump that calm him, or lead him away from potentially dire decisions or steer him in what they deem as more positive directions.

They must have the patience of Job since they and others have to explain things to the President again and again.

“Fear” is a good book. One which will likely confirm the fears of many readers while angering others for its negative portrayal of Trump.
