Next week's Helsinki summit poses the risk that President Trump could make a rash offer to Vladimir Putin in an attempt to improve U.S.–Russian relations. It's possible he might recognize Moscow’s annexation of Crimea, assent to Syrian President Assad’s continued rule or waver on America’s commitment to NATO.
The big picture: As much as Trump may want to turn the page with Putin, his recent call for a one-on-one meeting without aides is risky. Putin is a shrewd negotiator. A conciliatory approach with Russia has not worked out for the past three American presidents or a long list of European leaders, and it likely won't for Trump either.
