Cheney last week:
"As I’ve watched the events of the last few days it is clear once again that President Obama is trying to pretend we are not at war," Cheney said. "He seems to think if he has a low-key response to an attempt to blow up an airliner and kill hundreds of people, we won’t be at war. He seems to think if he gives terrorists the rights of Americans, lets them lawyer up and reads them their Miranda rights, we won’t be at war. He seems to think if we bring the mastermind of Sept. 11 to New York, give him a lawyer and trial in civilian court, we won’t be at war.
"He seems to think if he closes Guantanamo and releases the hard-core al-Qaida-trained terrorists still there, we won’t be at war. He seems to think if he gets rid of the words, 'war on terror,' we won't be at war. But we are at war and when President Obama pretends we aren’t, it makes us less safe. Why doesn’t he want to admit we’re at war? It doesn’t fit with the view of the world he brought with him to the Oval Office. It doesn’t fit with what seems to be the goal of his presidency — social transformation — the restructuring of American society. President Obama’s first object and his highest responsibility must be to defend us against an enemy that knows we are at war."
Well, not quite:
Here are two examples from the above linked site that prove Darth Vader has a selective memory, just like Giuliani, Matalin, and Dana Perino:
The fifth paragraph of his inaugural address : "Our nation is at war against a far-reaching network of violence and hatred."
In a February 2009 CNN interview: "I think it is very important for us to recognize that we have a battle or a war against some terrorist organizations."
You'll have to visit Politifact for the rest.
