Is there a case for conspiracy theories about 9/11 and the Iraq war? About 10 minutes into the ultra-low-budget documentary 'Loose Change,' now making its way around the Internet, that late, great genius of addled truth-telling, Hunter S. Thompson, is heard giving his gonzo opinion of the way the American press behaved after 9/11. "Well, let's see, 'shamefully' is the word that comes to mind," he says. The kernel of truth in all the conspiracy theories is that the Bush administration's biggest supporters and closest political allies have benefited mightily from its policy of open-ended war. Halliburton, Vice President Dick Cheney's old company -- which is all about both oil and defense -- has seen its stock rise from about $12 a share to about $80 a share under this administration. ExxonMobil, which has contributed mightily to the Republican Party, has seen its stock soar from about $32 to $64 since Bush took office. Share prices in both companies, and in their industries, were plunging before the Bush administration came to office in early 2001. 'Loose Change' doesn't present a plausible case for conspiracy, only a collection of innuendoes. But the invasion of Iraq, well, that's a rather different matter. As a whole raft of books by former members of the administration, Bush admirers and outside analysts have established over the last couple of years, the president and vice president were hell-bent on toppling Saddam Hussein even before September 2001.
