All evidence indicates the NYPD and FBI are on the trail of a major terror plot whose reach stretches from Afghanistan to New York to Colorado, and who knows where else. Good huntings.

The raids in Queens … along with confidential briefings given to members of Congress, left no doubt that U.S. counterterror operatives are mightily concerned about an effort to wreak terrible havoc.

There has been a tendency to shrug off busts as targeting homegrown wanna-bes who had a tough time getting their terror acts together.

You heard that in the Fort Dix case and in the Riverdale Jewish Center case and so on and so forth ad nauseam.

But this case has the earmarks of an ambitious nightmare, complete with overseas engineering.

It is also terrifying in that the suspects are believed to have planned to attack using easily made and devastating bombs. …

It is a truism of our age that America’s radical Islamist enemies need win only once, while U.S. intelligence and law enforcement agencies must win every time.

They have done the job magnificently for eight years, and they must have all the resources to continue the fight without carping and second-guessing.
