Bad headhunters will modify your resume without your permission and submit it to companies without asking you
Good headhunters will work with you to tailor your resume to each opportunity and ask you to make sure an opportunity sounds like a good fit before submitting your resume
Bad headhunters who submit your non-tailored resume first and don't tell you can cause problems when the Good headhunter submits another resume for the same candidate (you). Unfortunately, there's not much you can do about this except apologize for the mix-up and hope the hiring manager/company is understanding.
I wouldn't recommend "firing" the bad headhunter (unless you're actually paying him money, which would be odd since they usually get paid by the hiring companies) in case they luck into finding you a good opportunity. But you should firmly ask him to check with you in the future before changing/submitting your resume.
Governments are elected to serve their people. The US President is no different than other nations' heads of state in that regard.
And I find it interesting how so many people remember everything we do that they didn't like, but so quickly forget the good.
They remember that we invaded Iraq without full support from the members of the Security Council. Yet they forget we freed the Iraqi people from a tyranny that regularly raped and murdered its citizens, dumping their bodies in mass graves, and twice attacked its neighbors.
They forget the US military's aid to tsunami victims abroad, our protection of much of the world against threats from their neighbors, and our funding of vast portions of the United Nations budget.
The US government did all of those good things and more while acting in the interests of the United States. To say that our government acting in our interests is at best a neutral thing misunderstands the nature of human relationships. Acting in one's own interest often helps others too.
In 1984, citizens were encouraged to spy on each other and report possible dissidents to the authorities. So yes, this is very Orwellian.
As Oscar Wilde said:
Religion: a large, wealthy, powerful cult.
Cult: a small, impoverished, powerless religion.
