The Obama administration, faced with the question of whether the series of events in Egypt that led to the ouster of former president Muhammed Morsi was a coup or not, have decided not to make a final judgement in the near future. In doing so, they have, by default, declined to call it a "coup," ensuring that the U.S. will continue to provide $1.5 billion in annual aid to the country.
Here's why, according to the Associated Press (hint: it has a lot to do with that continued aid):
The administration has been forced into difficult contortions to justify not declaring a coup d'etat, which would prompt the automatic suspension of American assistance programs under U.S. law. Washington fears that halting such funding could imperil programs that help to secure Israel’s border and fight weapons smuggling into the Hamas-controlled Gaza Strip, among other things seen as critical to U.S. national security.
The non-decision leaves a door open for the administration to call the 2013 overthrow of the Egyptian government a coup in the future, but that would probably happen only if the U.S. loosened a restriction requiring the government to cut off all foreign aid to a country in the event of a coup. There are already a few members of Congress interested in pursuing those changes, including Republican senators Jim Inhofe and Bob Corker.
