"The biggest problem with Trump is he lacks courage and backbone"If you're arguing that Trump can't force Putin to do another meeting, sure. But I'm sure you heard Putin say "Next time in Moscow" at the end of their meeting. Bottom line, I think that Putin values diplomacy quite a bit. I don't think Trump values it nearly as much, but he at least values it a bit, or this meeting wouldn't have even taken place.
