The USA does drone strikes all the time, not only against minor targets, but with egregious collateral damage. Listing examples isn't even worth the energy because this is common knowledge and a simple google search would reveal hundreds if not thousands of these killings.

It was US Military leaks via WikiLeaks that first got Julian Assange onto the USA's hit list, and if and when they get their hands on him, they will make him disappear into a gruesome privatized prison system where he will have no right to be heard, because he published things the government didn't want people to know about.

I don't care if I, personally, will fall victim to this. Trusting the USA is a stupid thing to do, and you have to accept that they are capable of doing a great deal of harm to anyone they want to, regardless of nationality.
