As TPM notes, it seems like the London bombings were based on ideas developed in Iraq. As we’ve seen, it doesn’t match up exactly because the devices were crude with little chance of causing mass casualties had they gone off, thankfully they didn’t.
Here’s my question, why did Afghanistan stay local? Why did the mujahidin stay in Afghanistan and not export themselves to the Soviet Union? Or, to put it another way, why is Iraq flowing past its borders? Is this simply Al-Qaeda ideology? Strike at the infidel? It just seems so ineffective if you want freedom for you Muslim brothers and sisters, you stay and fight with/for them. What is different between the US occupation of Iraq and the Soviet occupation of Afghanistan?
