Donald J. Trump and Vladimir Putin are going to meet later this month in Helsinki, Finland.

You know that already.

Here’s the kicker. The two men are going to spend some time by themselves, with only an interpreter present, in the same room.

There won’t be any senior aides. No secretary of state. No foreign minister. No national security aides.

Just the two of them.

Wow! What can go wrong with that?

Putin’s a battle-hardened veteran of summits with U.S. presidents. Trump is, um, not so experienced at this level of diplomacy — and I use the term “diplomacy” with extreme caution as it regards the president.

I’m jittery in the extreme about what Trump might give away to Putin in that one-on-one session with the former head of the KGB, the spy agency that used to dig up dirt for the Soviet Union.

Oh, and do you believe Trump is going to challenge Putin in any meaningful way about the Russian meddling in our 2016 election?

You can stop laughing any time now.
