I don’t want to write on this topic at length, so I’m just going to leave you a few links to back up this claim:
The costly 2003–2010 US-led Iraq War was largely inspired by Christian beliefs.
Dr Muhammad al-Sammak … says “Most of the US presidents are very religious and George Bush is one of them. They definitely act according to their religious beliefs.
“For example, the late US president Ronald Reagan predicted in a TV interview that his generation would live to see the Battle of Armageddon. This is very biblical. No person would use such terms unless he was supported by his religious beliefs.”
Rumsfield’s daily “Worldwide Intelligence Updates” from the Pentagon often had covers with martial Bible quotes and, at least sometimes, photos of soldiers in prayer. (Easier to send ’em to die if you know their souls are saved, eh?) This story was broken by GQ (Flash slideshow – HTML here) and covered in numerous outlets like HuffPo and the Colbert Report.
Consider the way Bush referred to the war on terror as a “crusade” and conflated Iraq, which had no connection to al-Qaeda, with the al-Qaeda terrorists who attacked on 9/11. Well, they’re both Muslim; I can see how Bush could have trouble keeping them straight.
