Washington's opinion might well have changed and, as noted in other comments, an armada of nuclear ICBMs does negate the distance that he referenced. Regardless of the hypothetical, isn't it clear that Trump IS meddling and not following Washington's injunction? (Also applies to Israel/Gaza.) In family and community (and internet) dynamics, meddling in other people's quarrels often leads to blowback. (Yes, I'm aware of the irony of making this comment on HN.) Is it really any different on the global stage? My genuine question: What are the best criteria for deciding when getting involved is better than remaining on the sidelines? Do those criteria apply at both hyper-local and global scales, or this there a phase transition in applicability?
