Well without the military you would be most likely speaking german japanese or russian and probably not having this nice theoretical conversation on the internet right now
Unfortunately, a lot of people seem to assume that if America wasn't 'in charge' in the world, we would all be oppressed and wouldn't lead the life we do. I believe that many people need to let go of their ethnocentrism, and perhaps consider that the people who founded the United States came from Western European nations, and that all those nations have some period in their history of oppression, human rights abuses, etc., along with the United States (which currently wages an illegal war against the Iraqi people, and has committed many atrocities that we simply don't hear much about). This isn't to say that these nations (including the United States) aren't made up of people with good intentions, but that the powerful people in any nation will do what they must to advance their interests. This is much easier to do when we de-humanize people of the rest of the world.
History has shown, time and again, that everything runs in cycles. Civilizations rise and fall, and many of the greatest civilizations of the past were vastly larger (in terms of land size and percentage of the world's population) than the United States is today. All of these nations (or nation-like groups, such as the Mongolians) had some aspect in their military abilities that allowed them dominance over those they fought. Some factors in the Roman empire which lead to their dominance was their advanced war machines, strong economic structures and a strong central government. However, even the Romans were eventually overthrown by advancing 'barbaric' tribes such as the Saxons in the British Isles, etc.
We cannot predict what will happen to the United States in the future; there are simply far too many factors that will determine where dominance lies in the world. However, there are several problems with the current structure of Western society that will certainly weaken it over time. Our rates of consumption through our capitalist society will certainly cause our culture to collapse, as our current rates of consumption
cannot continue. Currently, (using the method developed by Mathis Wackernagel) people in high-income nations need 6.4 hectares of productive land for each person, but there is only 2.2 hectares of ecologically productive land for each person worldwide. This means that we cannot sustain our lifestyle without crushing the quality of life for humanity worldwide.
We may be taught that Western society is a
meritocracy (1. an elite group of people whose progress is based on ability and talent rather than on class privilege or wealth. 2. a system in which such persons are rewarded and advanced), but this simply isn't true. We are taught to believe that if you work hard, despite your circumstances, you will 'succceed' in life. If you think about this carefully, you will begin to realize just how untrue this is. We still employ a system of elitism in which the majority of wealth is inherited, and it isn't what you do, it's who you know that will get you somewhere. Of course, this isn't true in all situations, but truly, the wealthy get wealthier, and the poor stay poor. However, the poor in our western nations do not undergo the extreme conditions of poor people worldwide. This poverty correlates directly with our capitalist modes of consumption.
The IMF (International Monetary Fund) and World bank are largely responsible for much of the poverty worldwide. Please, this explanation is EXTREMELY simplified: After WWII, many nations had collapsed economically, and the United States emerged truly as a world power. Due to this, the IMF and World Bank lent out billions of dollars to many nations to jump-start their economies. Unfortunately, (and this still happens today), the economic system that these institutions tried to impose simply didn't work like they had in the United States (the US had grown into it's economy, slowly developing over time and the people of the United States adapted to it). Simply stated, the loans didn't work. Now these nations are all in debt to institutions such as the IMF and World Bank, and since the United States has such strict labour, wage, and safety laws (compared to peripheral nations), these institutions basically set the standards under which the people of peripheral nations operate. Needless to say, this system has exploited them and basically ensures that standards are kept extremely low in these nations. Peripheral nations need economic investment to avoid defaulting on their loans, so they must encourage investment by lowering environmental, labour, and safety standards. This keeps poverty alive in the world.
It is sad that we truly produce enough food in this world to feed every person on the planet, but with a dominant capitalist system put forth by the most powerful nations, food simply goes where the money is. Not to mention the thousands of acres of land that are used for cash crops instead of food production. Interestingly, our modern agriculure system is actually very inefficient when compared to swidden agriculture. The United States (and other western nations) could learn a lot from Cuba, which currently supports an extemely stable and sustainable agriculture system. Cuba hit what is called 'peak oil' after the collapse of the Soviet Union, and basically had to learn to operate with a fraction of it's former petroleum imports. Currently, we are close to hitting (or have already hit) peak oil in Western society, and changes must be made or our lives as we know them will collapse.
Corporations are running the world as we know it, and I believe that as long as profits are the primary motivation, the world will continue to be bathed in pointless wars, poverty, hunger and evironmental devastation. the US government actually requires
by law that corporations' must consider their 'bottom line' before
anything else. If you would like more information on corporations, watch 'The Corporation,' a Canadian made documentary.
I won't even begin to explain the time bomb that China is. With it's huge population, and absolutely exploding growth, we cannot begin to imagine the destruction possible to our world if they adapt lifestyles like the United States. Fortunately, we currently have the ability to change our system, but it must happen soon or the future of humanity (not just the United States) is in serious trouble.
