Any power, no matter how reasonable in design, can be abused. But it is Congress, not the courts, that should check the president. Supreme Court justices are unlikely to substitute their judgment on the use of troops and military necessity for that of the commander in chief and our elected representatives. Congress can use its appropriations powers to specifically prevent the president from reallocating military and civil funds to build a border wall. And it can resort to impeachment to counter anything it considers to be abuse of power.
