http://geography.about.com/gi/dynamic/offsite.htm?site=http://www.lib.utexas.edu/maps/iraq.htmlIraq has the following borders
With Iran 1,458 km,
With Jordan 181 km,
With Kuwait 240 km,
With Saudi Arabia 814 km,
With Syria 605 km,
With Turkey 352 km
Total: 3,650 KM
First these borders must be shut down. These 3,650 km are not all equal, very few people are coming from Kuwait but that still leaves 3,210 miles to patrol. A General rule of thumb is one company for every Kilometer (This is do to the need to maintain 24 hour surveillance, provide relief and a reserve to back up the troops on the line. Now some areas can be covered by Planes, but only those areas where people are NOT traveling. If people are traveling (and Bedouins live throughout the whole area) you have to have people on the ground. Thus you need at least 300,000 men just to secure the borders (Assuming a company of 100 men and 3000 KM of Borders).
The total land area of Iraq is 432,162 sq km of which only 13 % is arable (i.e. the part between the Tigris and Euphrates Rivers). This 13 % equals 56,181 square Kilometers. This is the important part of the Country, the surrounding desert is NOT important and can e ignored except for making sure not an avenue to get supplies to the insurgents
To give you an idea of what we are talking about, a typical American County is about 900 sq KM. A typical American County is roughly 20 miles by 20 miles or 30 km by 30 km. How many men do you think you will need to control an American County? The City of Pittsburgh Police Patrol just 1/3 of Allegheny County Pa with 1500 men (Thus in a NON-insurgent area you need about 4500 police officer to keep the peace). New York City has 39,111 officers in its five Boroughs (Counties in almost every other part of the Country). That comes to over 7800 officers per county.
Now NYC is going to be higher than most other areas, but as you can see the numbers of 4-8000 per URBAN County is NOT unusual. Rural Counties will have less, but as you can see just to control the area you need at least 1 man per Sq KM (4000 men dived by 1000 sq KM per county and you get 4 per Sq km per urban area, we can assume rural areas need less but 1/4 less than an urban area. Remember we are ignoring the desert, we are talking only of the farm-able parts of Iraq, thus a ratio of 1 soldier per see km starts to sound about right).
Thus you need at least 56,000 troops to occupy the "peaceful areas" of Iraq.
As to the actual insurgents, the general rule of thumb is 10 to 1, i.e. your army has to exceed his army by a factor of 10. Given the general estimate of the insurgents is about 50,000 men, you are looking at an additional 500,000 men to fight off the insurgents.
Thus the total number of men needed is about 850,000 men. If this number sounds familiar it should, American generals were throwing that number around BEFORE THE INVASION PLAN WAS FINISHED. Iraq under Saddam maintained a 1.7 million man Army for comparison.
Please note we are talking about boots on the Ground, not air, Artillery or Armor support. Some Air, Artillery and Armor Support can replace the boots on the grounds but sooner or later it comes to boots on the grounds that prevents the enemy from moving and getting supplies, thus you need all three areas covered, the borders, the "Pacified Areas" and troops to fight the insurgents whenever they pop up. The US does NOT have the troops to do this at the present time. The New Iraqi Army will not have them.
Thus Condi is telling the truth the Iraqi Army will NOT be this large, it can never be this large without popular support (Which it does NOT have). The problem for Condi is that while she has conceded the above, she does NOT want to give up Iraq, thus she will say anything she can to justify staying in Iraq no matter how bad it gets.
