France’s terror rampage ended Friday as police killed three Islamists, but not before they had paralyzed much of the country, taken more hostages, and killed at least four more innocents. Europe and the U.S. had better brace for more such attacks, while reinforcing the antiterror defenses, moral and military, that have come under political assault in recent years.

The biggest question raised by Paris is whether it presages a new offensive by homegrown jihadists carrying European or U.S. passports who are inspired by al Qaeda or Islamic State. Officials say one of the killers was trained by the al Qaeda offshoot in Yemen, and we can expect other such links or sympathies.
It’s tempting but probably wrong to think that France has a unique jihadist problem because of its relatively large Muslim population (about 7.5% of the country) and the immigrant ghettoes where they congregate. These certainly are breeding grounds for radicalism. Yet the United Kingdom has Birmingham, the Islamist petri dish for the London subway bombers, and the U.S. sheltered the killer Tsarnaevs in Boston and the Somali immigrants in Minnesota who’ve gone to Syria.
