What role did the United States play in creating and implementing alliances?
• Domestically (in the United States)
• Internationally (with other countries)

The united states has had to rely on military and relational alliance since its creation. Domestically, the american government has had to involve its citizens in matters of state, and also ensure the safety, and even military intervention on behalf of its citizens. This is due to the fact that they are its first and foremost ally. To make this possible and achievable, the american constitution has made provision for the importance of its citizens above every other. Externally, the united states has several allies with whom it has made pact with. This pacts can range from providing military support when need be, to providing economic and social support. The major allies of the united states are within NATO, which was formed during the cold war era to bolster america's chances of winning in the case of a war outbreak between the united states and the USSR. Till date, america has kept its end of the bargain even going as far as shouldering the major responsibilities of NATO, which some Americans believe is uncalled for.
