These critics have set up a straw Obama, a weak and naive leader who allegedly takes terrorism lightly, thinks that playing nicely with terrorists will make them stop, and fails to understand the threat that the United States faces from violent extremists. Mr. Cheney said that the incident had made "clear once again that President Obama is trying to pretend we are not at war." Likewise, Republican Study Committee Chairman Tom Price (R-Ga.) called on Mr. Obama to "recognize that we are at war with a murderous enemy who will not relent because we heed political correctness, acquiesce to international calls for deference or close the detention facility at Guantanamo Bay." Rep. Peter Hoekstra (R-Mich.), the ranking Republican on the House Intelligence Committee, said that Homeland Security Secretary Janet Napolitano "and the rest of the Obama administration view their role as law enforcement, first responders dealing with the aftermath of an attack. And we believe in a forward-looking approach to stopping these attacks before they happen."

There are two ways to show how baseless these attacks are: examining Mr. Obama's words and examining his actions.

Words first. "Evil does exist in the world," Mr. Obama said in accepting the Nobel Peace Prize. "Negotiations cannot convince al-Qaeda's leaders to lay down their arms." In his weekly radio speech Saturday, he disposed of the war-vs.-law-enforcement canard, pointing out that in his inaugural address he made it clear that "0ur nation is at war against a far-reaching network of violence and hatred and that we will do whatever it takes to defeat them and defend our country, even as we uphold the values that have always distinguished America among nations." "

But actions speak louder, and Mr. Obama's actions -- often at the cost of enraging his party's liberal base -- have also demonstrated tenacity and pragmatism blended with a necessary reassessment of the flawed policies of his predecessors and a recommitment to the rule of law. He wants to close the Guantanamo Bay prison, which is all to the good given its stain on the national character, but he has delayed that goal until acceptable alternatives can be found. He has brought criminal charges against some terrorists, but he has also sent others to be tried by military tribunals. He has invoked the authority of the executive to have lawsuits dismissed because they risk exposing state secrets. In addition to the new troop deployments, he has aggressively used predator drones to strike at terrorists, including outside Afghanistan. Even before the failed attack, his administration has been working aggressively with Yemeni authorities to deal with extremists there.

It is possible to disagree with the administration's decision to bring criminal charges against the suspect in the failed airplane bombing, Umar Farouk Abdulmutallab, although we think that was the proper course. It is possible to fault, as we have, some of the administration's public statements in the immediate aftermath of the attack. And as the president has acknowledged, the incident revealed failures in intelligence and in security screening that must be urgently identified and corrected. The country would benefit from a serious and bipartisan effort in Congress to ensure that the lessons of the Christmas attack are learned. A groundless campaign to portray Mr. Obama as soft on terror can only detract from that effort.
