A CATO Institute paper of 17 July, 2017 by John Glaser argues the following –

"The United States maintains a veritable empire of military bases throughout the world—about 800 of them in more than 70 countries. This forward-deployed military posture incurs substantial costs and disadvantages, exposing the United States to vulnerabilities and unintended consequences. The strategic justifications for overseas bases—that they deter adversaries, reassure allies, and enable rapid deployment operations—have lost much of their value and relevance in the contemporary security environment."
