Iran's foreign minister will not be attending the Davos summit in Switzerland this week, the organisers said Monday, stressing it would not be "right" after the recent deadly crackdown on protesters in Iran.

The bigger issue, Bremmer said, is that "his closest advisers are reluctant to tell him hes making a big mistake. And that can get you into trouble."

Bremmer added that Modi faces no urgency to respond to Washington's demands. "It is not urgent for Modi to respond to Trump in the way he wants."
