Now I want you to look over your three sentences and try to reduce them to a single sentence. If it was, look over what you've written. For a premise is a simple, solid statement, in the same way that a house foundation is a solid, simple structure. When I work with people struggling with writing a premise, most often what they're trying to use their premise to tell their story, i.e., the characters went here and did this, this is the plot, etc. Again, that leads the writer down the road of mistaking character goals and desires for what's at stake in their story itself .
Frugality leads to waste.
This premise is too general. It is not specific about what kind of events in history, how these events act on some group of people in a way that a story would offer some resolution. War leads to senseless destruction. What's at stake in this story is whether the destruction of war can be avoided. The fulfillment of this premise would be, perhaps, that a character who initiated events that led to a war believed they could protect themselves from the ruin of war, but they could not.
