Tor is funded by the US government, not the US military per se. The same US gov is funding research and efforts of breaking it. It's funding it to saveguard free speech and all that good stuff, and it's funding the attack to safeguard American supremacy (and maybe something about terrorism and crime).

Somehow it seems as wonderfully inefficient as it seems perfectly reasonable. And if you don't think it's reasonable, doesn't that just make more sense? It's the USA!

Is Tor imperfect? Yeah, probably. But it's the best tool out there atm. Is Tor intentionally imperfect? No evidence of it. Is reality a strange place to be? Definitely. Are Tor people completely untrustworthy? What's trust got to do with good code and crypto?
