Meddling in the internal affairs and politics of other nations has been part of U.S foriegn policy, with a dare to exagerate- probably since we first ever had a foreign policy. It is distastful and no way to treat friends- I agree.
As far as non-American forumites commenting on American politics- considering the many U.S. policies that have global impact I would see it as a like right and also like a neighborly extension of ideal of free speech we so covet here in my beautiful nation. So discuss away I say!
Also- what the hell is a "Sook"? This seems to be an Australianism and I am quite unfamiliar with it. It seems to mean, from context, as someone exagerating for a sympathy or emotional effect. Am I close?
