Nobody says it aloud but the underlying dispute is about the evaluation of the geopolitical scene. For most Europeans Russia isn't the threat that the USSR was. We simply don't feel the need to waste our money on defence any more.
I think a lot of Americans feel the same way about our own military. Why do we keep doing this? People asked the same questions even during the Cold War, about the building up of nuclear weapons, about wars such as Vietnam.
And it's correct to say that Russia really isn't the threat that the USSR was. Moreover, during the Cold War, I think they mostly exaggerated the threat of the USSR anyway.
But back then, it was the Republicans who were making a big thing about the "evil empire," while it was the Democrats who favored a more peaceful approach. Now, it seems to be reversed (although a lot of Republicans still appear to be stuck in Cold War mode as well).
You mean: create any conflict to rectify the existence of the globalized military?
The cold war is over. But “It is difficult to get a man to understand something, when his salary depends upon his not understanding it!” - Upton Sinclair.
That's why the US military-industrial complex hasn't adapted to the new reality.
I don't think they even want to adapt. It's not really good for America in the long run, to be wasting resources on pointless adventurism. Yet that's just what they're doing.
Americans like their power fantasies. Only that they are getting more and more unrealistic over time.
I think most Americans just want to survive at this point. A lot of people seem to be coming to the realization that they'll have to face a new reality. A lot of things we took for granted in the past may not be there in the future. I would hope this might encourage a more practical outlook, as opposed to grandiose, abstract myths about American exceptionalism, the "shining city on the hill," and all the other nonsense Americans have been spoon-fed since birth.
