Both kinds of persecution—undertaken by extragovernmental groups as well as by agents of the state—have come together in Egypt in the aftermath of the Arab Spring. On Oct. 9 of last year in the Maspero area of Cairo, Coptic Christians (who make up roughly 11 percent of Egypt’s population of 81 million) marched in protest against a wave of attacks by Islamists—including church burnings, rapes, mutilations, and murders—that followed the overthrow of Hosni Mubarak’s dictatorship. During the protest, Egyptian security forces drove their trucks into the crowd and fired on protesters, crushing and killing at least 24 and wounding more than 300 people. By the end of the year more than 200,000 Copts had fled their homes in anticipation of more attacks. With Islamists poised to gain much greater power in the wake of recent elections, their fears appear to be justified.

Egypt is not the only Arab country that seems bent on wiping out its Christian minority. Since 2003 more than 900 Iraqi Christians (most of them Assyrians) have been killed by terrorist violence in Baghdad alone, and 70 churches have been burned, according to the Assyrian International News Agency (AINA). Thousands of Iraqi Christians have fled as a result of violence directed specifically at them, reducing the number of Christians in the country to fewer than half a million from just over a million before 2003. AINA understandably describes this as an “incipient genocide or ethnic cleansing of Assyrians in Iraq.”

The 2.8 million Christians who live in Pakistan make up only about 1.6 percent of the population of more than 170 million. As members of such a tiny minority, they live in perpetual fear not only of Islamist terrorists but also of Pakistan’s draconian blasphemy laws. There is, for example, the notorious case of a Christian woman who was sentenced to death for allegedly insulting the Prophet Muhammad. When international pressure persuaded Punjab Gov. Salman Taseer to explore ways of freeing her, he was killed by his bodyguard. The bodyguard was then celebrated by prominent Muslim clerics as a hero—and though he was sentenced to death late last year, the judge who imposed the sentence now lives in hiding, fearing for his life.

Such cases are not unusual in Pakistan. The nation’s blasphemy laws are routinely used by criminals and intolerant Pakistani Muslims to bully religious minorities. Simply to declare belief in the Christian Trinity is considered blasphemous, since it contradicts mainstream Muslim theological doctrines. When a Christian group is suspected of transgressing the blasphemy laws, the consequences can be brutal. Just ask the members of the Christian aid group World Vision. Its offices were attacked in the spring of 2010 by 10 gunmen armed with grenades, leaving six people dead and four wounded. A militant Muslim group claimed responsibility for the attack on the grounds that World Vision was working to subvert Islam. (In fact, it was helping the survivors of a major earthquake.)

Not even Indonesia—often touted as the world’s most tolerant, democratic, and modern majority-Muslim nation—has been immune to the fevers of Christophobia. According to data compiled by the Christian Post, the number of violent incidents committed against religious minorities (and at 7 percent of the population, Christians are the country’s largest minority) increased by nearly 40 percent, from 198 to 276, between 2010 and 2011.

The litany of suffering could be extended. In Iran dozens of Christians have been arrested and jailed for daring to worship outside of the officially sanctioned church system. Saudi Arabia, meanwhile, deserves to be placed in a category of its own. Despite the fact that more than a million Christians live in the country as foreign workers, churches and even private acts of Christian prayer are banned; to enforce these totalitarian restrictions, the religious police regularly raid the homes of Christians and bring them up on charges of blasphemy in courts where their testimony carries less legal weight than a Muslim’s. Even in Ethiopia, where Christians make up a majority of the population, church burnings by members of the Muslim minority have become a problem.

It should be clear from this catalog of atrocities that anti-Christian violence is a major and underreported problem. No, the violence isn’t centrally planned or coordinated by some international Islamist agency. In that sense the global war on Christians isn’t a traditional war at all. It is, rather, a spontaneous expression of anti-Christian animus by Muslims that transcends cultures, regions, and ethnicities.
