Many American commentators, those from the liberal and leftist mass media, would agree that Trump is an insane militarist, an ugly, lecherous tyrant who has made one wrong step after another, and consequently, his impeachment and replacement by a more appropriate leader would lead to a more sound US foreign policy. Thus, the entire problem is reduced to Trump as a person. This is hardly the case. Trump's policy represents the views of a broad segment of the American elite. Unable to understand the US' withering ability to maintain its global hegemony and misreading the end of the Cold War, it engaged in reckless actions, and on occasion, almost insane verbalization.
The collapse of the USSR was seen by the US elite not as a winning lottery ticket delivered by Gorbachev, but as an affirmation of US socio-economic and military superiority. "Preventive" wars, actually wars of aggression, were launched by Democratic president Bill Clinton against Serbia/Yugoslavia (1999) and later by Republican president George W. Bush (2001 and 2003) against Afghanistan and Iraq. The ruling "neo-cons" did not even bother to moralize about the reason behind US actions.
