In a January 26 op-ed in the Iranian daily Kayhan, the paper's editor, Hossein Shariatmadari, who is close to Iranian Supreme Leader Ali Khamenei, called on Muslims to unite in a retaliatory attack on American, European, and Israeli "sensitive centers" because of "the war crimes that these countries are committing in the Gaza Strip" and because of their support for Israel.
In his op-ed, Shar'iatmadari stressed that American and European civilians must be harmed in these attacks, so as to make the U.S. and the European countries change their policy towards Israel. He further called for harming Israelis worldwide, and explained that Islamic regimes that prevent an Islamic attack on Israel must be toppled, because
they are defending the enemy.
Following are excerpts from Sharatmadari's op-ed, which was titled "The Defenders of the Enemy": 
"The slaughter being carried out by the Zionists in Gaza - which includes the mass murder of Palestinian men, women, and children, cutting off the electricity, water, and fuel, stopping the supply of medicines and food products - along with various other savage crimes, is disgraceful for the Zionists, and for America and its European allies.
"However, it is even more embarrassing and disgraceful for, first and foremost, the heads of several Islamic countries, [including] Egypt, that is insisting on adhering to the abject Camp David Accords and closing the Rafah border crossing [to the Palestinians]; for the cowardly and characterless rulers of Bahrain and the U.A.E., who awarded a prize to the murderer [i.e. President Bush] of the oppressed Palestinian people during his recent trip to the region; and for the Saudi [royal] family, that bears the appellation 'Custodian of the Two Holy Places' but is indifferent to the crimes and violations of the infidel Zionists in the Muslim holy places, and so on.
"But aren't most of the sensitive centers of the Zionists, of the Americans, and of some European states that support Israel already situated within the arms' reach of the Muslims? And aren't the Zionists [vulnerable] and located within arms' reach of the Muslims at the four corners of the earth? What human and legal basis can prevent an attack on these centers and people? Why must the savage, blood-letting Zionists and Americans be permitted to choose the field of battle as they wish? [Why are they permitted] to besiege the oppressed Palestinian brothers and sisters and their children, on the land that belongs to that helpless people, and to shoot at them night and day and to massacre them?
"America and its European and Zionist supporters must know that their support for Israel's crimes will cost them very dearly. Once they discern that this support will cost them the property and lives of their citizens, they will doubtless reconsider their support for the savage Zionists... And didn't the Imam [Ayatollah Ruhollah Khomeini] instruct that if every Muslim pours out one bucket of water, there will be a flood that will sweep away Israel, and destroy it?
"Every time a movement rises up against the Zionist occupier and acts to liberate its homeland, America and its allies accuse it of terrorism, and every state that supports these movements is punished. Why wouldn’t the Muslims act the same way, and attack all the supporters of the Zionists everywhere in the world?
"There is a legal view valid in both the Shi'ite and the Sunni school that it is permissible to attack anyone whom the enemy uses as a shield in the war against the enemies of Islam. Therefore, if some heads of Islamic states prevent the Muslim peoples from attacking the Zionists - thus constituting a shield that prevents support to the persecuted people of that region - it permissible to topple these defenders of the enemy."
