Ballpark estimate: US military Personnel in 130 nations, 900 overseas bases. - Politifact

• For the personnel question, we turned to a Sept. 30, 2010, Pentagon document titled, "Active Duty Military Personnel Strengths by Regional Area and by Country."
• For this question, we turned to an official Pentagon accounting of U.S. military bases around the nation and the world, the "Base Structure Report, Fiscal 2010 Baseline."
• Given the incomplete figures available from the Pentagon, Paul’s topline figures -- 130 nations, 900 bases -- are plausible when active military operations are included.
• we think it’s worth pointing out that many of the personnel deployments and facilities included in Paul’s number are fairly minimal in nature. On balance, we rate Paul’s statement Mostly True.
