This is a question that shouldn't even be asked if we lived in a sane world. Whenever fine ideas are touted, people always manage to screw it up, so we have to add in caveats for the dismally stupid.
Everyone has the right to pursue happiness - as long as that happiness does not infringe on the rights of others. It's so obvious, yet some people just don't get it.
Just because the constitution guarantees freedom of speech, it does not mean that you can use it to make the lives of others miserable.
The right to protect one's territorial and sovereign rights by armed force does not include the right to protect one's way of life by armed force. You cannot invade, nuke, or blockade a country to save a few cents on the price of gas or guarantee future supplies of energy. That would be theft by any definition.
The right to pursue one's personal happiness is one of the highest ideals penned by a government. Somehow, that ideal has been twisted at the national level in America to promote greed, war, and life in ignorance. Wealth without risk, rewards without effort, and information without wisdom. - That is the kind of life reserved for animals in zoos, and cannot possibly be regarded as anything but sedentary and useless.
