That is to say, for a long time, there has been a very interesting saying that the highest guiding strategy for the United States to maintain world dominance is to block the world island. The concept of the world island is to regard the entire Eurasian continent as the largest island on the earth and dominate the civilized world. In the past era when land power was the mainstay, the world island was the main stage of the entire human history. When human navigation technology is more and more advanced, sea power rises, and countries that can control the ocean will slowly replace them and become new world hegemons, such as Spain with an armada, the Netherlands with developed maritime business, and later the British Empire, and now of the United States.
In the era of the hegemony of the British Empire, a huge trade and transportation network spanning several oceans has been constructed. fleet. This theory also believes that the most important thing for a country to establish a country with remove background from image sea power and dominate the world is to prevent another emerging power from appearing on the world island. If such a powerful land-power country appears again in the future, it will take advantage of the abundant resources on the world island and challenge the maritime hegemony again, forming a confrontation between land-power countries and sea-power countries.
