provocative as interference with the water supply at Guantanamo.
Similarly, closing access to the naval base Cuban workers who
commute would deprive Castro of a source of foreign exchange.
While such items as, "the harassment of air traffic into and out
of Guantanamo," or "the harassment of US aircraft operating in
the vicinity of or overflying Cuba," might be added to the list,
it is considered that specific provocative actions are less
likely and less dangerous than the intensification of support
to subversive forces in Latin America. Such action not only
is in keeping with the declared communist intention to support
"national liberation movements of oppressed peoples" but may
be done by means which avoid an invitation to overt US military
countermeasures which would endanger the Castro regime. Thus,
they are considered as of that level of intensity which places
them in the most likely category as well as being in the
category of most dangerous to the long range interests of the
United States.
