If you mean right in the legal sense: Because of freedom of speech? If they think they have something to say about someone, and be it the leaders of my country, then they have the legal right to say it.
If you mean right in a moral sense, I guess my question still is: Why not?
If you are negatively affected by the actions of a leader of a foreign country ... why should you not have a right to criticize that?
If you have some constructive criticism as to how the leader of a foreign country is doing their job badly and how they could to it better ... what would be the use of not saying so out loud? Couldn't that possibly even be a contribution to their country?
I really don't see why having contributed to something would have anything to do with whether you should criticize it or not?! I can see how maybe you don't get a direct say in who gets to be the leader, but that's quite different from criticizing them, isn't it? I haven't contributed to Equifax either, but I still don't see why I shouldn't criticize their leadership?! Or should I? Why? Why not? And how is a country fundamentally different from a company in that regard?
That's a very odd sentiment. Do you believe most of the posters here also have no right to criticize China for these actions? Or that noone here has any right to criticize north Korea? I don't think anyone here pays them any taxes.
It's your freedom to do so, plus you have that right written in the law which we're not protected by.
For me, I just don't comment something I don't understand, I'm not living in the US, so I can't feel what Obama's doing.
Because of that, how can I make a comment that is appropriate? I can't even make a comment that's accurate (Judging by those late night shows I watched on Youtube).
Now about tax, I think it's actually you paid your government to do what they want. When they did something wrong / you don't like it, of course you can complain about it.
But as a foreigner however, if the US government did some negative thing on us, the most effective way I think is to blame our government for letting it to happen.
BTW: Of course, in China we have anit-US (Or Japan etc) prides from time to time, just I'm not a fan of it.
If somebody didn't contribute to your country, how can he/she has right to criticize people who do?
