When do I stop getting excited when someone hurts my country?
I'm all for the USG to try to improve the position economically and politically in the world so long as they respect certain bounds of decency while doing so. Spying the the politicians and citizens of other countries in order to gain advantage is not decent or fair, the same way you wouldn't want your boss or your co-workers to spy on you to keep you from a raise or promotion.
The US, China, Russia and the UK are among the biggest sociopaths insofar as countries interacting with other countries go. I'm not proud of that, and I would hope we could meet with other countries and their leaders on a fair playing field and discuss things as adults instead or resorting to bullying.
What it crosses to me is the boundary between loyalty to one's leaders and loyalty to one's country. Obama is going after Snowden, and I can either support or not support that action, that's my right as a citizen. But when another country takes action against my country, that suddenly becomes an act of agression directed at me, and every other citizen of the US.
That's not "nice", or "classy" at all.
Ecuador is providing protection to a whistleblower that is trying to help you question an unconstitutional program and reign in abuses. In a way that makes Ecuador a greater defender of the US Constitution than the USG.
I don't know about you, but my loyalty is to the system of governance and rights laid out by the Constitution before some amorphous geographic shape determined by natural boundaries and history. I see Ecuador as helping the person that is helping protect the Constitution. I don't necessarily know their motivations or agree with the reason they may be acting the way they are, but I do know that the World needs more people like Snowden, and people willing to go to bat for Snowden, if we are going to be able to defend the Bill of Rights and other documents/policies outlining basic human rights.
P.S. Threatening economic sanctions isn't "nice" or "classy" either. The US is as guilty as Ecuador for making this into an adversarial tete-a-tete.
