So The Guardian's headline may be the simplest (but plausible) analysis if the US/Israeli war against Iran you'll see this week:
'Middle East war could be decided by who runs out of missiles or interceptors first'!
Obviously its a bit more complicated than that (see article), but the sub-editors' summary is pretty functional as a strategic analytical statement!
