The first amendment seems to be much broader than establishing a national religion. If a government (a foreign country) was heavily theocratic, would it amount to an establishment of religion? If so, would congress be forbidden from passing laws that put an embargo on it? A law that says "companies cannot do trade with given country" would be in violation of the first amendment if the country were also a religion, right? I think a theocratic nation could be considered an establishment of religion. Is that not true?
