two reasons why the USA has a military influence on other countries - power and spending
This means that as the US is the largest spender on defence this
can force other countries (such as China and Russia) to spend
more to compete. Many countries look to the US for help in times
of conflict. For example, the US’ spent around $811 billion on
their military in 2022 – the highest in the world and
more than double the second largest.
