Thanks for the reply. Totally agree this is a shifting situation and I am linking to older data. And the essay I linked to I wrote was from 2009. And also totally agree that the US military has many missions (arguably too many) all over the place so it can be hard to allocate costs to a specific mission (especially the costs of creating and maintaining military infrastructure like an aircraft carrier or submarine or various bases or training costs and so on).
That said, the link you supplied has a title "Saudi Arabia has paid $500M toward the cost of US troops in country". That's probably like a week or less of fuel costs for the US military overall? Don't know specific to that deployment.
Granted, this is from 2010, but consider the magnitude of the numbers here:
https://www.sciencedirect.com/...
"This paper presents the first estimate of United States military cost for Persian Gulf force (CPGfp) derived entirely by a quantitative method. An activity-based cost (ABC) model uses geographic distribution of aircraft carriers as a proxy allocator of Department of Defense (DoD) baseline cost to regional operations. Allocation follows simply from DoD data that since 1990 no less than one aircraft carrier has been continuously on-station in the Persian Gulf; that eight are required to keep one on-station there; that the Navy has had eleven-fifteen carriers since 1990; and that Army and Air Force units are virtually never deployed to combat operations without Navy units. For 1976-2007 CPGfp is estimated to be $6.8Ã--10^12 and for 2007 $0.5Ã--10^12 (2008$). This substantial military investment is not a remedy for the market failure at the heart of regional security problem, which is oil market power. When CPGfp is added to economic losses attributed to market power in another recent study (Greene, 2010), the severity of this market failure becomes more apparent."
Those values are $6.8 trillion dollars over that 1976-2007 time period and then $0.5 trillion in one year. $500 million from Saudi Arabia is 1/1000 of $500 billion. Just a token amount. Even if that deployment cost was now just 10% of what it was, it would still be a huge number. (And of course, that is just the monetary costs, not the personal costs.)
As the authors suggest, and others like Amory Lovins in Brittle Power, using fossil fuels without including the cost of defense in the up-front at-the-pump cost leads to a market failure. Capitalism can't work well unless purchases reflect the true costs.
In the book Brittle Power (or was it a related book like Energy, Vulnerability, and War?) it was suggested that the cost of just one year or so of the Persian Gulf Deployment Force in the 1980s would have been enough if invested in energy efficiency and renewables to eliminate the need for foreign oil.
And that is part of why Amory Lovins and others essentially argue locally-produced renewables and energy efficiency have been cheaper than fossil fuels -- all things considered -- since the 1970s. It's just a market failure that benefits some special interests and costs the US taxpayer.
That situation is shifting, agreed, but where are the apologies for the decades of bad policy? Or at least, where is the discussion and learning about such things so it does not happen again? The shift to renewables like solar PV seems more to do with a bunch of dedicated people chipping away for decades at making renewables cheaper than fossil fuels even given a tilted playing vastly in favor of fossil fuels.
I am all for spending money on national security. The questions is how to spend our money effectively to achieve real security? As I suggest here:
https://pdfernhout.net/recogni...
"We the people need to redefine security in a sustainable and resilient way. Much current US military doctrine is based around unilateral security ("I'm safe because you are nervous") and extrinsic security ("I'm safe despite long supply lines because I have a bunch of soldiers to defend them"), which both lead to expensive arms races. We need as a society to move to other paradigms like Morton Deutsch's mutual security ("We're all looking out for each other's safety") and Amory Lovin's intrinsic security ("Our redundant decentralized local systems can take a lot of pounding whether from storm, earthquake, or bombs and would still would keep working")."
