I agree. Not responding shows courage, restraint and wisdom, not weakness.
It was a tit-for-tat move by Iran in response for Israel bombing Iran's embassy in Damascus and killing its general.
In the exchange, Israel drew blood, Iran failed to do so. So that's a sort of win.
And it was a useful test of the iron dome, which showed it could operate on a massive scale.
That ought to do. Israel got away with its assassination at little cost. It could have been worse. And the risk of a far worse outcome in future rounds of tit-for-tat attacks is very real.
Bank the win.
