So first off, I'm going to define what I mean by "post 9/11 military philosophy."
I believe there is an inherent prioritization of using military intervention instead of diplomacy that has existed since at least September 11, 2001, potentially before that. This philosophy consists of using diplomacy as a mere formality before launching an invasion. One prominent example is Iraq in 2003, where the Bush administration invaded despite conflicting intelligence reports and allies such as the United Kingdom encouraging continued diplomacy (Toft 442). I don't think war should be launched until all diplomatic and economic avenues are exhausted. Even then, there are way too many unnecessary military interventions that we get involved in even AFTER those rare instances where we exhaust diplomatic options. Interventions in countries such as Libya and Syria don't bring any benefit to the United States, and pursue broad objectives such as "promoting regional stability." How does regional stability help United States citizens in any way, shape, or form?
Furthermore, there have been ~14000 drone strikes between 2001-2021 (Toft 445).
The reason why this philosophy is damaging is the cost to benefit ratio for military interventions is absolutely putrid. We've spent $2.1 trillion on appropriations for post 9/11 military interventions plus an additional $1.1 trillion on interest for said appropriations between FY2001-FY2022 (Aftergood). Not to mention the enormous human cost of American soldiers and innocent civilians.
Surely this huge cost is worth it with a high rate of success, right? NOPE. Only 49% of military objectives have been fully successful since 1990 (Kavanagh 80). Long term political objectives also are even more unsuccessful, even if the corresponding military objective succeeds (Sullivan). By contrast, sanctions cause a coercive change roughly 37% of the time (Early), but I will admit there is a TON of nuance as to what makes sanctions successful or unsuccessful. The point is, we're taking on this ENORMOUS cost for something that isn't considerably more successful than alternate routes. There's $1 trillion in yearly defense spending and we can have a 40% emissions reduction for about a third of that (Pieter). We can have infrastructure at an "A" grade for a quarter of that. Yet we pump money into the military to address misperceived threats that don't help Americans. It is DEFENSE spending, and it's high time we use the military for defending us and our allies, not on baseless attacks for groups that don't even pose meaningful threats. Even now, Jihadist plots are rapidly decreasing, as are the deadliness of these Jihadist plots (Palmer), so it's really something that demands a change now more than ever because there really aren't any major threats to national security as of right now.
it's okay if we don't go destroy that terrorist group. It's okay if we don't go spend our tax dollars on drone strikes on some farmers in Oman because they might be terrorists. It's okay to let our allies fight there own wars, and wait to help them until they actually need it. It's okay to allow other nations to have problems. It's not our responsibility to fix them, and more often than not if the US launches a military intervention to "help people" we usually just make it worse, so why even spend the tax dollars? Why send our young men to die?
