Just to clarify, I'm not wearing a tinfoil hat, I just have seen the circumstances of some drone attacks: against US citizens in places where no war was declared and with collateral damage shrugged off. From the US perspective, it is an easy means of getting rid of people they don't like with neither the need for judicial proceedings nor formal declaration of war. The only thing that is really stopping them right now is that Assange is currently in a highly populated part of the UK, and not in the middle of nowhere in Yemen.
The US would certainly not do a drone attack against a first-world nation, as the political fallout would be immense. They do have a great many other levers to use that the public would never see...
