Opinion | Iran’s attack on Israel reveals weakness - The Washington Post

This was not a simple act of unprovoked aggression. Don't forget that the air assault was a response to an Israeli strike on an Iranian diplomatic compound in Syria that killed a top commander and several officers of Iran's Islamic Revolutionary Guard Corps. In recent months, and in fact over several years, Israel has assassinated numerous Iranian military officials and nuclear scientists and generally wreaked havoc on Iranian assets without suffering significant consequences. 

Iran's leaders, shaken by the killing of top military brass, felt they had to respond with a show of strength. Not doing so would signal impotence to Israel and Iran's Arab adversaries, as well as a restive domestic population that is increasingly eager to see the end of the theocratic regime...

The missiles fired by Hamas cost about $600 each, and so they are about 100 times less expensive than the Iron Dome interceptors. The total cost to Israel of firing all of its interceptors is around $48 million. If Hamas fired 5,000 missiles, the cost would be only $3 million. 

Thus, in a carefully planned and executed strategy, Hamas accumulated over time a large number of relatively inexpensive missiles that it knew would overwhelm the Iron Dome defensive capabilities. Unfortunately for Israel, the Hamas attack represents a very clear example of military asymmetry: a low-cost, less-capable approach was able to defeat a more expensive, high-technology system...
