>The U.S went to wars, killing hundreds of thousands of civilians to force open markets to its products
This is a standard Marxist explanation for U.S. overseas military intervention [0]. It is also largely wrong.
Let’s look at the data. After 16 years of obscenely expensive American intervention in Iraq, that country exports more to China than the U.S., and imports more from China and Turkey together than from all other trade partners combined [1]. Likewise, Afghanistan today imports almost nothing from the U.S., but relies heavily on exports from China and Iran - two major U.S. competitors [2]. This is, of course, geographical common sense. If anything, recent U.S. wars have opened new markets for China, their number one geopolitical competitor.
Looking further back, Germany, Japan, and South Korea have all developed into financially independent trading partners. Far from U.S. capital dominating Japan, Americans were afraid for quite some time that Japanese cars, electronics, and industrial equipment would completely displace their American equivalents.
