I'm glad you recognize all of this "anti-globalism" as a racket. Whether his motivations are logical is completely irrelevant to me though, and you're right that he has behaved logically. I have to ask...so what?
The way Russia is happy to accommodate Assange, Snowden, Jill Stein, the Trump campaign, and anybody in town who is interested in taking a piece out of America (whether they have good points or bad points doesn't matter in the least), it of course makes sense for anti-American actors to take advantage of their money, their airtime, and if need be, their spies. And we have a duty to ourselves to fucking curbstomp them.
Globalism in terms of ideas, economics, and safety has been one of the greatest forces for human good... ostensibly.
On the other hand, it has undermined the core principles of living: culture, individual autonomy as well as collective identity, and through the specter of trade-over-everything has allowed the West to turn a blind eye to new soft and hard forms of authoritarianism.
The racket as per Russia, is that Russia wants power from this and their own identity to pursue that power. There aims are not noble, but it is hard to say America's aims pretend to be noble nowadays.
America is the greater force of good, though, more from the bones of some past Eagle of the Enlightenment, that glides on as a zombie husk spreading the carrion of all encompassing consumerism and the ugliest parts of a vapid culture, eaten down to the very heart, and interested in a pitiless future of technologically driven social control and whatever empty ethos of desire the new philosophy of post-post modernism can conjure.
All that aside, I would still take Globalism... but we are too blind to make it work for good, maybe now, maybe forever.
I guess that comes to the only real question. If we are breaking all of our own laws and principles in secret, and want to break even more laws and principles to squash the Wikileaks bug, are we not going further down the relativist road in the wrong direction... where it matters the most? He is not a terrorist, or a dictator, and while a cad, is not so much an evil man, yet we would make compromises to destroy him rather than win an honest debate? I respect the need for nations, certainly republican nations, to fight for their benefit... but let's hang him, and anyone else who has in truth gone too far, by honest means, not on a Swedish rape-lie.
