Many administrations have had faults battling for America.
Few times in our history we step up efforts. For instance, the Japanese bombings, where Americans responded heavily.
American enjoy gov blame, not excepting the accounts it takes be apart of a global society.
The limited (very limited) exit effort makes best sense. " Provide for the common defense."
There's too much run to not except responsibility within the "End the War" movement. Leaving less concern for the Iraqi.
This administration did what it did at the time. Thus far, there's been no further attacks!
