Any strong presence that you’re referring to would have to be reinforced with violent action or threats of violent action so America would still rule the world, or “America” would still rule the world. If Assad was using chemical weapons in a war that really isn’t our concern then why get involved? Do we get involved in any African nations affairs which also have human rights violations? What of China? Assad is the rightful ruler of Syria and I don’t like that but we have no business getting involved in Syria. The same thing goes for Ukraine, the people Russia “annexed” want Russia to stay. What business do we have in Syria, Ukraine or a hundred other countries if not to meddle in business that doesn’t concern us. The American Constitution is the greatest manmade document ever written but not only is our government ignoring it, we the people abandoned it too I hate to say.
