That empire was close to what they were. When we give what we have up it will not be as nice. Britain dying gave us two world wars. Because we did not want to be a global policeman as empire was shoved into our face. We were the economic power by the turn of the 20th Century..The Founders fought quite a war against the most powerful Imperialist EMPIRE in the world, at that time.
Have you every fought a war against an EMPIRE far larger and stronger than your nation? So that your people could be free?
Someone who wanted a correct view of the Founders would find that an important piece of information. You seemed content to ignore it, before passing judgement.
