An effect of frequent fighting in the Middle East was that many people lost their lives. Since the unification of Saudi Arabia, that went from 1902 to 1932, conflicts in the Middle East increased their frecuency. In a brief review, we find the Arab-Israeli Conflict, the Iran-Iraq War, the Gulf War, the American incursions in Afghanistan and Iraq of the 20th century, the Syrian Civil War, the Arab Spring, and many other conflicts.
The cost in lives that these conflicts have represented is very high. There are no exact figures for the number of deaths that the convulsed political situation in the Middle East has left, but it is estimated that between 8,000,000 and 16,000,000 people lost their lives from 1902 to the present due to conflicts in the Middle East.
Iron and steel--by the late 19th century the US became the world leader in iron ore and steel exports.
Access to natural resources and a lot of labor, the US was able to access iron ore which was a hot commodity and necessary for creating steel. If countries had the ability to create steel then they would just buy the iron ore. If they could not produce steel, then US Steel was the export for them. Steel industries dominated states like Pennsylvania, Ohio, Michigan, and Indiana.
<span>Assuming that this is referring to the same list of options that was posted before with this question, <span>the correct response would be that "iron rails were easily replaceable", since in fact that represented relatively permanent infrastructure. </span></span>
