Boomerang

In the long history of putsches and coups, the worst case scenario for the plotters is usually to succeed...only to fail.

In other words, to breach the existing order and take control, only to discover that the new situation is unsustainable.

Moscow 1991, Brutus and Cassius etc etc.

This is because the uncoupling from continuity becomes permanent even if the change of personnel at the top does not. The Soviet Union and the Roman Republic were doomed.

When the boomerang comes back to hit the golpistas on the nose, the regime that replaces them can legitimately do away with everything which came before without having to play the game according to all the old rules.

And so it will be here if Arévalo's accession is blocked, temporarily.
