Final answer:
The United States maintains an extensive military presence globally, with a defense budget of about 1.3 trillion dollars.

Step-by-step explanation:
The United States has a significant presence in global affairs, reinforced by its substantial military expenditures. The annual defense budget for the U.S. is approximately 1.3 trillion dollars, illustrating the scale of its commitment to defense and international security. This investment maintains the U.S.'s ability to uphold formal or informal agreements to defend 37 countries and operate over 700 military installations in roughly 130 countries.
The U.S. history of military interventions is extensive, with involvement in countries such as Panama, Kuwait, Somalia, Bosnia, Haiti, Kosovo, Afghanistan, and Iraq since 1989. These interventions demonstrate the U.S.’s active role in international affairs, particularly in response to conflicts and crises that align with its foreign policy objectives.
Given the enormous figures, it's evident that U.S. defense initiatives have both a vast scale and a significant global impact. The defense budget and military installations are a reflection of a wide-reaching strategy to exert influence and maintain global stability as perceived by U.S. policymakers.
