What statistical insights does First Harvest Ministries provide on the impact of military aid, referencing the '70% rule'?

First Harvest Ministries highlights a key economic point often called the “70% rule.” In teaching on U.S. military aid to Israel, it is explained that roughly 70% of that aid must be spent back in the United States with American defense contractors (for example, companies like Lockheed).

This means:

• The money largely funds American manufacturing and technology
• It supports U.S. jobs and industry rather than being a pure “giveaway”
• Aid functions more like an investment with a domestic return on investment (ROI)
