We base #autogolpe reigns on this Wikipedia list:

The list has issues so we focused on 20th & 21st century #SelfieCoup. We ignored entries that lack cross-references w/ dates in other Wikipedia articles.

We of course included Napoleon, because Napoleon

We base birth & battle dates for all Medal of Honor recipients on this list:

We base the list of ongoing wars on this Wikipedia page:

en.wikipedia.org/wiki/United_St…

Oddly, SECDEF's official website doesn't provide a history for the position

We base FBI directors' tenures on the FBI's official history page:
fbi.gov/history/direct…

The website shows an overlap between William J. Burns and J. Edgar Hoover, so we set Burns' end date to May 9, 1924.

We base NO end date for the War on Poverty on this Wikipedia chart compiled from U.S. Census Bureau data:
en.wikipedia.org/wiki/Poverty_i…

We suppose President Johnson's War on Poverty might "end" if the 19.0% poverty rate were #halved; but U.S. poverty has never dipped to even 10%.

We base 23 December 1971 as the start of the War on Cancer on the U.S. government's official cancer website:

We base the list of Secretaries of State on this Wikipedia list:

history.state.gov/departmenthist…

We consult Wikipedia for Acting Ambassadors:
en.wikipedia.org/wiki/List_of_a…

It appears Wikipedia bases UN ambassadors' tenure dates on their "presentation of credentials" and we consider it a perfectly valid choice.

However, this account centers on the United States' prosecution of GWOT. We shall base tenures on their appointment to the mission.

We base the list of U.S. Ambassadors to Afghanistan on the official website:
en.wikipedia.org/wiki/List_of_a…

We base the list of designated Foreign Terrorist Organizations (FTOs) on the U.S. State Dept website:
state.gov/foreign-terror…

We base the list of Canada's designated terror groups on their official public safety website:
