Setting the stage - again

It was quiet for a few weeks. Even reports that Iran was backing off. But now...Iraq blast pinned on Iran-linked militants

The U.S. military on Saturday blamed the deadly bombing of a pet market in Baghdad on Iranian-backed Shiite militants, raising concerns that Shiite extremist activity could escalate and jeopardize waning violence in Iraq.
"I'm not saying that yesterday Iran ordered the bombing of the pet market," Smith said. But, he said, the attack had the "fingerprints" of a group that had been trained, equipped and facilitated through Iranian connections.

So what you are really saying is - no proof. But what the hell - blame Iran and get the public pumped and angry and ready for an attack.

Now if Pakistan doesn't throw a wrench into the machine - Tehran here we come.
