Is US surge plan in Iraq working?

The military objectives of the US troop surge in Iraq "are largely being met", the top US military commander in Iraq, Gen David Petraeus, has said.

The US surge can be successful if there is evidence of imminent US forces withdrawal without plunging Iraq in further violence. Many operations proved without significant consequences like the killing of insurgent leaders like Abu Musab al-Zarqawi or the capture of many other insurgents.

The Iraqi government will stand defenceless if the US troops withdraw from Iraq. The militias will have more power controlling areas and carrying out operations. There will be the risk of neighbouring countries, especially Turkey and Iran interfering with the affairs of Iraq, which can lead to regional tensions. It's very likely the US will continue its presence for a long time in Iraq by keeping military bases instead of a complete pull-out once security is handed over to Iraqi forces.

As long as there is no national reconciliation in Iraq, the insurgents will continue to thrive forcing the US to stay longer since the Iraqi forces are still unable to mount a stiff challenge to the insurgents and the suicide bombers whose sport is to detonate wherever leaving as many deaths and injuries as possible. Among the insurgents, there is always the death ratio of one suicide bombers against tens of injured and dead.
