The act of imperishable Brahman is incomprehensible to the ordinary minds but like it is said, God works in mysterious ways. America has been an instrument of God for hundreds of years now. Since it’s discovery and leading the world as a leader in all areas, America stands as a monarch that rules the entire globe maintaining the cosmic order. Irrespective of different Presidents holding the office and their motives, American leadership in the world has been like that of Krishna during the Dwapara Yuga.
Krishna and his entire Yadava race were like America and Americans of the present times. Although Krishna was the King of a small fort of Dwarka protecting the citizens that had to flee from Mathura, he was the real ruler of the whole world, King of Kings. Throughout his life, he fought against the miscreants and demonic rulers with the help of Yadava force and other countries, eliminated the wrong leaders and replaced them with the right leaders like Yudhistira.
Irrespective of the motive why US Presidents from the beginning went to war, the comprehensive act of America has been like that of Krishna. Wrong leaders like Hitler,Saddam Hussein and Japanese emperor have been deposed and people that govern with heart and mind have been given the power. Krishna fought and slayed every power hungry rulers and replaced them with better ones ensuring them his protection.
When he slayed Kamsa, he enthroned his father Ugrasena, when he slayed Jarasanda, he enthroned his son, when he slayed Paundraka, he enthroned his wife, when he eliminated Kauravas, he enthroned Pandavas. These are just few examples of Krishna’s contribution towards the welfare of humanity. American interference and diplomacy has had a similar impact knowingly or unknowingly. America has never conquered other countries and tried to annex them into their own. Instead, America has replaced autocratic and inhumane rulers with humane and kind ones.
In short, if we observe the geo-political scenario for last few decades, we can clearly see the cosmic order being worked out with America as a major instrument. If America was a person, you could consider him an incarnation of Vishnu
