While Bush focused like a laser on screwing up in Iraq, North Korea began its waltz toward nuclear (that's "noo-cleee--er") capabilities.
Fred Kaplan ("Rolling Blunder: How the Bush administration let North Korea get Nukes", Washington Monthly, May 2004) reports these January, 2004 events:
"Over the next two weeks, U.S. spy satellites detected trucks pulling up to the site where the fuel rods were stored, then driving away toward the reprocessing facility. When Kim Il Sung threatened to take this step back in 1994, Clinton warned that it would cross a "red line." When Kim Jong-il actually did it in 2003, George W. Bush did nothing.
"Specialists inside the U.S. government were flabbergasted."
