Answer 1

There will be no net or overall change in the GDP of the United States. 

Importation by the government causes an increase in the investment or purchase component of the GDP. However, because the exports of the country has a value equal to the imports, there is no net change in the GDP then. Net exports after all is the difference between the exports and the imports.
