Here is what I posted to a post from Prozac in a different thread on the topic regarding our national interest in the Pacific vs Europe:
Noone here has forgotten the whole lesson about US involvement in European instability. However, that lesson is receiving heavy scrutiny now because of its cost. And it should receive scrutiny. There are no "natural laws" or "rules" in geo-politics. We should always be adjusting our thought.
First off, I'm skeptical anytime mentions US foreign policy and "track record" or "history" in the same sentence. 200 years isn't history. Its a sneeze. China has seen continuous governance under a unified identify for over 3000 years. Sink that in a for a bit because its a bit amazing to think about. Sure they've had overthrows and invasions that took power, but they always remained predominantly identified as a single people (disregarding discussions of sub cultures like the Han, im talking specifically, how long has there been a "place identified as China"). So building trend data off of two events that happened only 20 years apart probably isn't prudent global planning on our part.
Second, saying that a secure "Europe" is better for American prosperity is a bit dishonest. Europe is a geographical feature that says nothing about where the global balance of power lies. Pre-WW2, many of those powers happened to be conjugated in Europe. Today? Not a single European player (outside maybe France in the UK as notable exceptions) has global influence. The center of power has shifted dramatically from Western Europe to the Pacific. The top 6 military power centers in the world on the Global Firepower Index all have borders on the Pacific Ocean. (8 if you count Britain and France's Pacific holdings) 6/12 of the largest economies are on the Pacific, including the Top 3, the US, China and Japan. The problem with the above philosophy is it puts WAY too much importance on how much influence Europe has on the world order in modern terms.
Third, we tend to have a lens that puts too much emphasis on the WW's as what happened in Western Europe. We forget, that they were global wars, and especially in WW2, most of the fighting did not take place in Western Europe. I promise you the Chinese don't frame their historic perceptions of WW2 as something that mainly occurred in Europe. As our #1 adversary, that should be something that we take important note of.
Fourth, having the basic premise that a continent cant organize their shit so we have to occupy and pacify them for our own successful aims just doesn't sound like a good long term strategy.
We invest 320K DoD personnel in Europe. That is literally 1/4 of our entire military, on one foreign continent. The largest military in Western Europe is the US military. Think about that for a minute, and then think about what your squadron could do with a 33% manning boost? To quote your terms, why are we spending "on peace and prosperity in Europe" when we should be spending on Peace and Prosperity in the United States, the largest threat to which, is in Asia.
I totally understand and hear your point of view. But I find it outdated and irrelevant with what is actually going on in the world right now. I think there is a growing crowd of skeptics that question if Europe is "worth" our investment
