Was the number too low and why, if so? I don’t know.
But I would still reply to your comment that the answer to your statement is simple: If tomahawk missiles were the sole budget item, a trillion dollars would obviously purchase more. But you have no ships, tanks, aircraft, spacecraft, soldiers, training, transportation… someone made a decision to have that number of missiles along with all the other weapons and systems. Was it insufficient? That requires investigation. But talking about the entire budget is… not applicable.
