I appreciate all of this in principle. But when we're currently looking at the United States, a country whose military spending dwarfs the rest of the planet combined, I find this justification rings hollow. Sufficient strength is not under serious threat. Perhaps, in centuries to come, a geopolitical situation may arise in which the US is closer to parity with other major powers, and it'd be safer for them to have a few proxies around.... is this distant, speculative situation enough to justify the enormous human cost here and now? I'd say definitely not.I would argue that as a general rule, the top consideration is self-continuation; I would classify that separately from self-interest, although there is significant overlap. If we assume as axiomatic that countries will have enemies, then any country has a duty to maintain sufficient strength to ensure that its enemy(-ies) cannot overwhelm it. This then sets us a notional boundary between maintaining sufficient power to be secure, and needless self-aggrandisement. Coercion of other states may be justifiable for the former but not the latter.
But where exactly is that boundary, in the endless unknowables of the future?
Besides, if we create these situations by destabilising other countries, they don't tend to be reliable. In general, through these actions the US achieves fleeting economic and military gain, not security for centuries to come.
Well, we have something of a case study (or the closest we're likely to get) in... Imperialism. The same justifications floated around for the European monarchies to keep their Imperial outposts all around the world, economically exploiting the native populations, conscripting them, selling them into slavery etc. This too was justified on the basis of the European countries' continued prosperity and security in centuries to come.Would our descendants really thank our moral decency if in 50 years it meant their way of life and sovereignty were in mortal peril - and likely also the values we intended to uphold?
I don't thank my ancestors for being a part of that, no. The values we intend to uphold aren't really "values" so much as naked selfishness if we deny them to others in order to horde them for ourselves.
I can see that justification, but I think it's been inflated into a false binary, and used to justify some terribly unnecessary stuff. There are other (diplomatic) approaches for checking the aggression of Russia and China that have a greater track record than trying to install a sympathetic government by force.And I'm entirely in your corner when it comes to a purely moral or ethical deliberation and that the current way leads to some truly terrible acts that often causes harm or death to lots of innocent people.
My dilemma in this discussion is a bit like the discussion around Pacifism. On a strictly ethical level I'm all for non-violence and refusal to use violence as a tool, but on a practical level I can also see that it is not a feasible ideology to hold onto as all it takes is for someone to decide to use violence and everyone else will either have to break their own ideology or be forced to submit. This is pretty much the same: intervention via covert action, military or economic means into non-hostile states is terrible and it'd be better if no one did it. But I'd rather that western democracies (even barely functional ones like the USA) do these things further themselves and thwart the ambitions of nations like China or Russia who are much, much worse and wouldn't hesitate to fuck Western nations up if they got the chance.
The latter can even backfire so spectacularly that it strengthens our geopolitical enemies. Look at Iran, or Cuba.
