In so doing the Marines had shown that a substantial American combat force could be brought to bear quickly in the remote areas chosen by the Communists as targets for their so-called "wars of national liberation." Furthermore, the MEU by relying on a vigorous civic action program, had established that a sizable Marine command could maintain its combat readiness almost indefinitely without eroding the respect of the indigenous population. Thus, General Simpson's Marines had created a solid foundation of mutual respect and confidence with the Thai people. This accomplishment alone would prove valuable when American military forces would be required to return to northern Thailand later in the decade. Against the backdrop of these accomplishments, the 3d Marine Expeditionary Unit's operations in Thailand could be assessed as having extended the tradition of the U.S. Marine Corps as an effective instrument of American diplomacy.
