I was surprised about his positive assessment of Binyamin Netanyahu and his negative assessment of Shimon Peres, as this is the opposite one would have expected from a Soviet / Russian diplomat based on their political positions.
Now I find in an Economist review of a biography of the late Jordanian King Hussein that he had a similar assessment of these politicians:
Mr Shlaim concedes that the king was occasionally naive and impulsive, and could put too much store on personality and too little on ideology. On this score, his most grievous misjudgments were briefly to prefer the right-wing Israeli leader Binyamin Netanyahu, whom he seemed to back (perhaps even tipping the scales) against Shimon Peres, whom he did not trust, in the Israeli election of 1996;
As Primakov claims to have counted himself a friend of King Hussein, that similarity may not be accidental. It would be interesting to know who influenced whose opinion in that matter.
