Even for liberals the following dots should be easy to connect – there are only two dots:

Iraqi Al Qaeda = Iran

For those who need some assistance you can find it here:

Iran was today accused by Britain of supplying Iraqi insurgents with the technology and explosives to kill its soldiers in the south of the country.
A senior government official, briefing correspondents in London, said that there was evidence that the Iranians were in contact with insurgent groups fighting coalition forces in Iraq.

“We think it has come from Lebanese Hizbollah via Iran,” he said, adding that the action could be an attempt to warn Britain off its demands that Tehran should abandon its controversial nuclear programme.

“It would be entirely natural that they would want to send a message ‘Don’t mess with us’. It would not be outside the policy parameters of Tehran,” he said.

The official said the explosives had come from Iran’s Revolutionary Guard but refused to be drawn on whether the corps were acting on the orders of the government in Tehran or were operating independently.

Iranians might want to reconsider that bulls eye they are painting on themselves (here and here at the end).
