Former US President Barack Obama spoke in a forthcoming book about “America's deep divisions,” and to what degree President Donald Trump's departure from the White House alone will not be sufficient to correct them.

In excerpts from the first volume of his memoir "Promised Land" (a Promise Land), which appears on the market Tuesday, and "The Atlantic" magazine published excerpts from it, Obama goes back to the past four years since he left the White House, and wrote, "It is more Concerned, it may seem that our democratic system is plunging into a crisis. "

He added that there is "a crisis rooted between two different visions of America, what it is and what it should be," condemning the striking of standards beyond the limits and abandoning things that for a long time were "an acquired" for Republicans and Democrats alike.

He welcomed the election of his former deputy, Joe Biden, as president of the United States, warning of a rosy vision for the years following Trump, adding, "I also know that one election will not contribute to solving the problem."

He explained, "Our divisions are deep and our challenges are great," but he stressed that he "hopes for the best" of the future, convinced that America can reflect "the best of what we have if we act with determination and broad imagination."

He talks that at the end of his presidency, he and his wife Michelle boarded Air Force One for the last time and traveled to spend a long, deferred break. In it, a person who is totally opposed to everything we have advocated is chosen to be my successor. "

In this 768-page volume, Obama also recounts his style of writing "with a pen, not on a computer," and the difficulty he encountered in shortening.

He also recounts how, during his eight years in the White House, he was searching for a quiet corner to smoke an "evening cigarette."

Obama's relationship with smoking and his announcement to quit were the subject of speculation during his 2008 campaign and first term.
