The book says the Trump administration was seriously concerned about the possibility of Hezbollah dragging the US into a “catastrophic” Middle East war. The recently-published book entitled “Fear: Trump in the White House” says that in February 2017, early in the Trump administration, top US officials were seriously worried that Israel could not defend itself against a possible attack from Hezbollah, should one ever occur. Such an incident would have had “catastrophic” consequences, the book says.
