U.S. foreign policy is defined by President Trump's belief in dominating the weak and giving deference to the strong.
There have been political realists emerging in Trump's administration subscribing to the same view.
Trump sees security not through spreading democracy but through power and domination.
The rise in realism is attributed to part to the insecurity of the United States.
Trump's belligerent policies and threats against peaceful neighbors could result in costly repercussions.
Conclusion: Trump's adoption of 'Neanderthal realism' does not guarantee the longevity of a great power. As the history of Athens showcases, brutality can lead to the downfall of an empire as noble ideas such as justice and respect for international laws are more enduring.
