But on the strategic level, there is a big difference between massive rocket fire on Ashkelon or Sderot and massive rocket fire targeting Tel Aviv or Jerusalem.
Tel Aviv is Israel's financial center. A barrage of missiles will paralyze the banks, take down the stock exchange and badly damage the economy. The stock market will respond immediately in a destructive manner – and Israel will find it difficult to recover from such a blow.
Jerusalem is the capital. The Knesset, the Supreme Court and government ministries are all located in the city. Targeting the capital is strategic as well.
Significant rocket fire on Ben-Gurion Airport will shut down Israel's main entrance and exit gate. Airlines will stop flying here. There will be no departures and no arrivals. This is a strategic blow, and Israel cannot afford such a situation.
Tel Aviv is home to institutions which are crucial for the State's existence: The IDF's General Staff is in the city center. Hitting it will not paralyze the army, but will damage it preparedness. The headquarters of major companies are located in the city. If their workers stay away from the office – perhaps in order to remain home with their children if schools are shut down – the economy will be paralyzed.
To a lesser extent, Ashdod – with its large industrial area, port and power station – is a strategic target as well. If a missile attack paralyzes the port, it will be a serious blow. Israel won't be able to fight for long with a paralyzed economy.
The attacks on London during World War II and on New York on September 11, 2011 are etched in global memory, have been recorded in the books of history and significantly affected leaders' decision making, up to a declaration of war. We must always remember that.
