No sooner did Cheney's boy Karl Rove give a speech about using war and terror to get republicans elected (last weekend, to be honest) than did they send out their PR puppy George W. to proclaim the obvious. Osama is important. Even if it directly contradicts what Bush said while lying about Iraq in his pre-War propaganda:
"I'll repeat what I said. I truly am not that concerned about him." President Bush, March 13, 2002
Bin Laden takes over for the tired and overused Saddam Hussein as the official tool for avoiding issues. They still don't care about Osama. He, to be honest, simply helps to shift the common people's attention away from the terrible Supreme Court nomination Alito. This is so fewer people contact their senators and complain about electing Samuel Alito as a Supreme Court justice, even if it requires a filibuster at this point.
Let's be serious. If they ever had been concerned about Osama, they would have used Saddam to get inside information on where Bin Laden actually is. Even though Osama and Saddam hated each other, anti-American people still trusted him and would have provided connections and, OH MY GOD, actual intelligence on Osama.
Instead, Cheney's Bush simply barks Al Qaeda and Osama whenever they need a distraction from more important issues - like getting Supreme Court judges elected that will permit them to torture and spy on Americans without any justification.
Especially now that the overwhelming majority views Iraq as a mistake, if not a blunder, lie, or an Abramoff/Delay-type approach to making close, personal friends and family rich with non-compete contracts.
