Petraeus works to halt foreign fighters.

But why would the "first thought" be that it would be someone on the U.S. payroll, "Freelancers? Jundallah? Someone else on our payroll?".

Out of all the possible choices available, why would the focus be on pointing the finger immediately at the U.S. and coming to a premature conclusion. It becomes a bit of a political Rorschach test.

And because as I stated the proxy war has been underway for years already and we are funding our own proxies who are killing Iranians.

None of this is happening in a vacuum. What Iran does in Iraq is influenced by what we do in Iran.

You want to play this game, there are going to be costs. Of course it could be that there is a hope that Iran is goaded into doing something stupid and getting caught red handed, which provides the pretext everyone is looking for to shift focus of our whole Middle East effort to confronting Iran rather than sorting out Iraq and Afghanistan.

Iran says U.S. aids rebels at its borders
The violence may be driving Tehran's efforts to back its own allies in Iraq.

BAGHDAD — A series of conflicts with insurgent groups along Iran's borders may be impelling Tehran to back its own allies in Iraq in what it regards as a proxy war with the U.S., according to security experts and officials in the U.S., Iran and Iraq.

Dozens of Iranian officials, members of the security forces and insurgents belonging to Kurdish, Arab Iranian and Baluch groups have died in the fighting in recent years. It now appears to be heating up once again after an unusually cold and snowy winter.

In recent weeks, Iranians have begun the now-routine bombardment of suspected rebel Iranian Kurd positions in northern Iraq, and guerrillas have claimed incursions into northwestern Iran.

Some Iranians blamed Sunni Arab radicals for an explosion Saturday that killed 12 and injured 202 at a gathering where a preacher criticized the Wahhabi form of Islam that inspires Osama bin Laden.

None of the groups appear to pose a serious threat to Iran, but Tehran regards them as Washington's allies in an effort to pressure it to scale back its nuclear program and withhold support for militant groups fighting Israel. American and Iraqi officials in turn accuse Iran of supporting Shiite Muslim militias and other militant groups in Iraq to keep the U.S. preoccupied and the Baghdad government weak.

Although a U.S. intelligence estimate in December undercut claims that Iran has a secret nuclear weapons program and appeared to lower the possibility of a direct military conflict over Iran's uranium enrichment operations, tensions over Iraq have increased. U.S. officials accuse Iran of backing Shiite militias close to cleric Muqtada Sadr that fought Iraqi government forces to a standstill in Basra and Baghdad two weeks ago.

Analysts say the anti-Iranian groups are tempting assets for the U.S. They say it would be a surprise if the groups were not receiving U.S. funding, but that the strategy would probably not work.

"It will give more encouragement to Iran's hard-liners to step up their own efforts to assist anti-American forces in Iraq and Afghanistan," said Bruce Riedel, a former CIA analyst now at the Brookings Institution, a Washington think tank.

Among the most active groups is the Party for Free Life in Kurdistan, known by its Kurdish acronym, PEJAK. It has hundreds of well-trained fighters along with camps in northern Iraq.

Iranian soldiers guarding the border are sometimes ambushed by PEJAK fighters. Iran responds with artillery attacks that send Iraqi villagers scurrying for cover. Border skirmishes last summer and fall between Iranian security forces and PEJAK left dozens dead on both sides.
