On Monday, President Trump made the crisis in Venezuela a central part of a rally in Florida. And yes, to rail against a socialist country where people quite literally don’t have enough to eat is a great implicit knock on potential 2020 Democratic challengers who embrace socialism, either in name or in the form of policies such as “Medicare for all” and free college tuition.

But Trump should be wary of attaching foreign policy threats to rhetoric motivated by domestic politics, as he did at the rally in Miami.
