You said Cheney didn't speak out while the administration "dithered" for 7.5 years in Afghanistan and Iraq. As Superfreak and I stated Cheney was all over the news during Bush's Presidency speaking out about what he felt the U.S. should be doing. It's not like the man sat in the background while not saying a word.
I understand you are trying to stick up for Obama you just picked a very bad analogy to do so.
No he was part of or running an administration that did just what he is attacking Obama for doing. If he disagreed he should have spoken up. I know he did not say a word so he clearly agreed when it was he and Bush doing the same thing.... Now that Obama is doing it, he attacks.
