Supporting efforts? Supporting what? We disbanded the entire Iraqi Army and it appears still to be incapable of securing its own country. The US Army in Iraq is what needs support.
We have done a pretty poor job at rebuilding their Army as well. At first we didn't think Iraq needed a real Army just a National Guard, because we wanted to keep Iraq weak and from starting anymore wars. But, then we realized we didn't have enough troops to secure the country and keep the other Islamic countries in the region from trying to destabilize it further. So late 2004 we started building a real Iraqi Army.
However, if you look at the numbers the US only wanted a 10 division Iraqi Army so when we maxed out the growth of the Iraqi Army 6-7 months ago we stopped adding troops to the Iraqi Army. The Iraqi hasn't really grown in half a year. It was about 128,000 troops 6 months ago it has about 132,000 troops today. The Pentagon needs to find a clue that the Iraqi Army needs to be more then doubled. Probably to around 350,000 troops.
That could be done in a shorter time then one might think, if the money is provided.
