Nothing

• The US and Russia arranged a summit between US President Donald Trump and Russian President Vladimir Putin in Helsinki.

• Experts say the US has nothing to gain and everything to lose from a meeting between Trump and Putin given current US-Russia relations and Trump's personal affinity for Putin.

•"But that seems to be the pattern of Trump's dealmaking," said one former State Department official.

• "We move the US embassy to Jerusalem and get nothing in exchange.

• We give the North Koreans a summit and get nothing in exchange.

• We pull out of the Iran nuclear deal and get nothing in exchange.

• This is par for the (Trump) course."
