When Trump met MerkelMarch 2017
It was a very curious case of non-interaction between the two politicians, where Trump used a steeple gesture throughout much of it - steeple gestures are associated with confidence and a position of authority. Merkel reinforced his authority position by orienting herself to him, Trump did not reciprocate and showed her little visual attention. The 'reverse' steeple gesture used by Trump here, down and pointing outwards, was towards the associated camera crews rather than her. They, rather than she, were the focus of his attention.
