In response to the worst attack on U.S. soil since Pearl Harbor, President George W. Bush told a joint session of Congress: “Our war on terror begins with al Qaeda, but it does not end there. It will not end until every terrorist group of global reach has been found, stopped and defeated.”

We have clearly failed to meet that goal. After more than 13 years of war, with thousands of Americans dead, tens of thousands of Americans wounded, and several trillion dollars spent, the U.S. and its allies are losing the war with radical Islamism. The terrorists of Islamic State are ravaging Iraq and Syria, Boko Haram is widening its bloody swath through Nigeria, al Qaeda and its affiliates are killing with impunity in Somalia, Yemen and beyond, and the Taliban are resurgent in Afghanistan. The killings in Paris at Charlie Hebdo and at a kosher supermarket are only the most recent evidence of the widening menace of radical Islamism.

Confronted with the atrocities in Paris, French Prime Minister Manuel Valls told his people on Jan. 10 that they were at war: “It is a war against terrorism, against jihadism, against radical Islam, against everything that is aimed at breaking fraternity, freedom, solidarity.”
