IBD is the only publication which has caught that KSM's affidavit demonstates AQ's tactical link to Iraq
"Of particular interest is the revelation about Mohammed's involvement in the '93 bombing. It shows a linkage not only between the '93 WTC attack and 9/11, but also between Iraq and al-Qaida.
We already know, for instance, that Abdul Rahman Yasin, the Iraqi responsible for carrying out the '93 bombing, found a haven in Iraq for a decade after the attack. Yasin worked closely with another al-Qaida operative, Ramzi Yousef, on the '93 WTC bombing.
For the record, Yousef is Mohammed's nephew. He was described by the National Commission On Terrorism's 9/11 report as 'the mastermind' of the '93 bombing. And according to U.S. intelligence, he got funding from al-Qaida.
Intelligence documents captured in Baghdad in September 2003 show that Yasin and the others received financial aid from the Iraqi government. This raises a big question: Why would Iraq, under international scrutiny for both WMD and sanctions, support a known terrorist with ties to al-Qaida? The only reasonable answer is, it wanted to keep Yasin quiet about Iraq's involvement.
There's ample evidence of Iraq's role in 9/11 too. The lead 9/11 hijacker, Mohammed Atta, met at least twice with Iraqi intelligence in Europe before carrying out the attacks. And Ahmed Hikmat Shakir, an Iraqi intelligence operative, attended a key meeting of the 9/11 hijackers and other al-Qaida terrorists in January 2000.
Upon capture, Shakir was found to be in contact with Zahid Sheikh Mohammed, brother of Khalid Sheikh Mohammed, Iraqi Musab Yasin, brother of Abdul Rahman Yasin, and Ibrahim Ahmad Suleiman, a '93 WTC conspirator."

The left understands the implications of KSM's confession. That's why they're so desperate to dismiss it as exaggeration.
