My original comment was made to poster Nervous Tick, in response to a general philosophy about warfare.
Nervous Tick made the point the warfare should be avoided as much as possible, but should be fully engaged if it is deemed necessary.
We are not fully engaged in Iraq...we have sufficient evidence that Iran is participating against us by proxy. A fully engaged war plan should not worry about borders. However, the political will to take on Iran is absent...thus the conflict in Iraq drags on.
Gulf Arabs eye Iraq role to counter Iran
And wouldn't they prefer to have American Troops in Iraq...
