Why should the us be isolated?

The United States should be isolated because the more we rely on other countries, the more they have our country by the scruff of the neck. All the jobs that we sent over seas for cheaper production should be brought back to provide more jobs for the citizens that are out of work. This could solve our problems with un-employment. Also, products that are proudly made in The United States are higher in quality and the people in this country would be more liable to buy these products because they know that they are supporting another American that needs money just as much as the rest of us. The oil that we are buying from the Middle East is also not necessary. We have enough land in the United States to harvest enough oil to be self-sufficeint and be able to stop buying oil over-seas. Several people believe that if we use too much then we will run out, what they don't know is that these resources are RENEWABLE. That means they come back over time.
