The Logic of Jonah

I can't argue with Jonah Goldberg's logic. It seems we invaded Iraq to make the Jihadists really mad, or something like that:

Indeed, isn't the determination of jihadi fanatics to defend Iraq by attacking London exactly the sort of evidence required to demonstrate a linkage between terrorism and Iraq? If America and Britain invaded Canada, Islamic terrorists wouldn't care. But when we invaded Baghdad, they immediately declared it to be the defining battle of their movement. Abu Musab al-Zarqawi, the head of al-Qaida in Iraq, has flatly declared that the future of their cause depends on the outcome of the fight in Iraq.
