Although the Phase I(aug 99) report does not mention preemption it certainly points out that prevention and deterrence will not be effective in the 21st century.
The phase II report(april 2000) plainly states:
"The magnitude of the danger posed by WMD compels this nation to consider carefully the means and circumstances of preemption"
This passage is to be found in the first paragraph on page 9 of the Phase II report.
Here is the link to all the Hart-Ruddman Commission reports from whence you can navigate. These reports should be required reading.
Are you suggesting that the Hart/Ruddman report is what is driving foreign policy? Are you aware that the administration dismissed that report in its entirety before 9/11? The fact that the word “preemption” is in the report does not support in any way your position that that is where the modern doctrine originated. I’ll give you a hint, it was about a decade earlier and Hart and Ruddman had nothing to do with it.
