First, this ignores that the USA benefits tremendously from trading with other countries, most of all with China. If this mindset was applied universally, the USA (and the world) would be worse off. It also ignores that treating countries as though they are enemies can become a self-fulfilling prophecy. It can increase the threat rather than decrease it.
Second, it's not necessarily in one's best interest to live in a "top dog" country. There are plenty of happy and prosperous people living outside the USA. The USA ranks 26th for median wealth. To give another example, even if China took the top dog spot, the average US citizen would still be better off than the average Chinese citizen.
Thirdly, I don't think the US remaining top dog is a realistic objective in the long term. In my opinion, it would be smarter to lead by example knowing that your successor will be judged by the standard you set.
