Is Trump's blatant launch of imperialism ,,,,,,, a sign of a global disaster?

The Monroe Doctrine was both a declaration of the Americas breaking free from European colonial rule, and also a declaration to Europe, by the rapidly growing United States, telling Europe, 'The Western Hemisphere is our sphere of influence, so don't touch it.' The Monroe Doctrine naturally declined after World War II , mainly because the U.S. diplomatic strategy shifted from 'regional hegemony' to 'global hegemony.' It participated in the two world wars where Europe was the main stage, and later NATO was formed, so mutual non-interference and isolationism The prerequisites were broken, and above all, imperialism, where great powers arbitrarily forced weaker nations, degenerated under the new world order. Through multilateralism and international organizations like the UN, the trend of valuing international legal consensus over unilateralism grew, and ultimately, Monroe Doctrine retreated into the shadows of history as a sinister legacy of the United States during its imperialist era. However, Trump's emergence has brought Monroe Doctrine back from the abyss; last December, President Trump formalized 'Donloism' by combining his own name with Monroe Doctrine, and by reinterpreting Monroe Doctrine in the past, he further reinforced its imperialist character. It is basic to define the Western Hemisphere as the exclusive sphere of influence of the United States, and in this region, especially China and Russia have been firmly stated not to be approached, and unilateralism has become even more blatant and powerful. For the benefit of the United States, there are no enemies or allies, and the use of military cards has become even more aggressive. Yet, through surprise operations at night , they dragged the Venezuelan president out of his bedroom and escorted him to the United States, and threatened to hand over Greenland, an autonomous territory of Denmark, a NATO ally, threatening to take military action if refused. The European Union   In response, the EU launched a barrage of imposing high tariffs on the affected countries, and withdrew from 66 international organizations, including 35 UN agencies. The United States, which has stated it will no longer support money for world peace, welfare, or improved relations, is clearly returning to the era of imperialism, where only the logic of power ran rampant.
