A head of state captured without congressional authorisation. Seven countries struck in a single year. A war-powers resolution that failed by a single vote. This is the category where the money trail and the constitution intersect.

Using the stronger word would be more dramatic and less true, and this is exactly the kind of substitution that lets an entire document be dismissed.
