How many US drone strikes occurred each year under the Obama, Trump, and Bush administrations?

1. How different sources count strikes — and why the numbers diverge

Datasets use different criteria: the Bureau of Investigative Journalism (BIJ) and Drone Wars count strikes in Pakistan, Yemen, Somalia and elsewhere and attribute many covert strikes to the CIA; news outlets sometimes cite BIJ totals; academic summaries report Bush’s total in the dozens and Obama’s in the five hundreds. For example, the Bureau’s tallies show Obama-era strikes far outpacing Bush’s (563 vs. about 57) and BIJ/related reporting is commonly cited in media summaries ^{[1] [4] [3]}.

2. George W. Bush: a modest but precedent-setting start

Reporting across multiple sources places Bush-era drone use as limited relative to his successors — on the order of a few dozen strikes. The Bureau and academic accounts note roughly 57 strikes during Bush’s terms, establishing the legal and operational precedents for later administrations to expand the practice ^{[1] [4]}.

3. Barack Obama: the dramatic expansion

Obama moved drone strikes from an occasional tool to a central counterterrorism instrument. The Bureau reports 563 strikes by drones/air strikes in Pakistan, Somalia and Yemen across his two terms, and other outlets and analyses place total Obama-era drone strikes at about 540–563 — far more than Bush ^{[1] [5] [3]}. Council on Foreign Relations analysis frames Obama as leaving “two terms and 540 strikes later” as his legacy ^[5].

4. Donald Trump: surge, reclassification and reporting gaps

Trump’s approach loosened Obama-era restrictions and reclassified some theaters as “areas of active hostilities,” which reduced reporting obligations. The BIJ and reporting cited by the BBC counted 2,243 drone strikes in Trump’s first two years versus 1,878 in Obama’s eight years — an indication of a major uptick early in Trump’s term; other compilers report different totals for specific theaters ^[2]. Coverage stresses that changes in policy and reporting rules undercut comparability ^{[2] [6]}.

5. What “drone strike” includes — CIA, Pentagon, and geographic scope

Important reporting differences come from whether trackers include only CIA-authorized strikes, only military strikes, or both; whether strikes in Afghanistan or in areas defined as “active hostilities” are counted; and whether airstrikes by manned aircraft are bundled with remotely piloted strikes. The Drone Wars and BIJ projects explicitly map and histogram strikes by quarter and by presidential term, showing methodological choices materially affect totals ^{[7] [1]}.

6. Civilian casualty reporting and transparency problems

Obama imposed a 2016 requirement that intelligence agencies report civilian casualties from strikes outside war zones; Trump revoked or loosened parts of that framework and re-designated some regions to reduce reporting obligations. That policy shift means available counts of strikes and casualties are less comparable after 2017 and that official tallies understate key details, a point noted by BBC and other outlets citing BIJ ^{[2] [6]}.

7. Competing perspectives and political framing

Proponents argue expanded strike campaigns degraded terrorist leadership with surgical precision; critics and human-rights groups cite higher civilian toll estimates and lack of accountability. Analysts and outlets repeatedly note the same pattern: each successive administration broadened or intensified the program while overtly different rules and disclosure make apples-to-apples comparisons difficult ^{[1] [8] [2]}.

8. What the available sources do not settle

Available sources do not mention a single, definitive per-year spreadsheet that reconciles every strike attribution across CIA and Pentagon databases for each calendar year of all three presidencies. They also do not provide a consensus number that harmonizes redefinitions (what counts as a drone strike) and reclassifications of geographic theaters ^{[1] [2] [7]}.

9. Bottom line for readers

If you want a conservative, cross-checked headline: Bush conducted roughly tens of strikes (≈57), Obama oversaw roughly five hundred-plus strikes (≈540–563) largely concentrated in Pakistan, Yemen and Somalia, and Trump’s early term shows a significant surge with BIJ reporting 2,243 strikes in his first two years — but methodological differences and policy-driven reporting changes mean year-by-year comparisons are imprecise and contested ^{[1] [5] [2]}.

Limitations: these figures come from public trackers and reporting cited above; official U.S. government tallies and exact year-by-year reconciliations are not consistently available in the cited material ^{[2] [1]}.
