What do the "anti-war" left think?

I’d have thought the leftwing blogs that claim to care so much about death and destruction in Iraq would be outraged that the Islamist insurgency is training children and using people with Down’s Syndrome to bomb civilians.

However, I have yet to see a single post from the left outraged by it. Surely it can't be because the insurgency is fighting the USA? Surely that doesn't justify using innocent people to bomb innocent people?

My question is this. Do those who opposed the invasion of Iraq and overthrow of the Saddam Hussein regime support or oppose the Islamist insurgency there?

Quite simply, if you have strong views on waging war against the Ba’athist Iraqi government, presumably you should also have views on waging war against the current one.
