I’m certain there’s no quantifiable way to address the difference between those phrases, and that this is rather a matter of opinion regarding what one thinks “massive” means in terms of military/political rhetoric. I think my point was made, despite my questions going unanswered.

Thanks for the discussion!

(I’m not continuing this discussion, since the interest here seems to be quibbling over one word of rhetoric.)

Tehran is waiting for Israel’s response to a massive missile attack as the conflict in the Middle East threatens to escalate.

Sounds commensurate to me :)
