It is important to understand why the MOAB (Mother of All Bombs) may have seen its second operational use in history:
Iran was planning to manufacture around 200 missiles per month, with ambitions to ramp up production to 500. Within three years, such a facility could have produced over 10,000 missiles.
Imagine the devastating potential to terrorize Gulf states, Israel, and parts of Europe—especially as Iran developed longer-range missiles capable of reaching the mainland United States. Now, that key facility has been destroyed ("caput").
