 SUBJECT
Situation in  Pakistan
...
While East Pakistani  leader Mujibur Rahman has stepped back a bit from a declaration of independence,  the full text of his March 7 speech conveys a harsher tone than the initial  summary reports, and it seems apparent that his retreat was tactical. He made  clear that something very close to independence, i.e., "emancipation," is his  goal and that his movement will not be deflected until that is achieved.  Noteworthy also is the fact that Rahman quite openly took issue with Yahya,  accusing him of "submitting to the declaration of a minority"  [West  Pakistan] and asserting that  his own Awami League is the only legitimate source of authority in the country.  
  
 Awami League  President Mujibur Rahman addressed a rally at Dacca racecourse on March 7  and called for a continuation of the "peaceful non-cooperation" movement against  the government, including the closure of all government offices and educational  institutions. He said that he would consider attending the National Assembly  session scheduled by President Yahya for March 25 if martial law were  terminated, the troops in East  Pakistan were withdrawn to their  barracks, and power was returned to the elected representatives of the people.

Our embassy in  Islamabad believes that Rahman's goal remains unchanged-"emancipation" of  East  Pakistan from West Pakistani  domination. This could still conceivably mean "full provincial autonomy" within  a united Pakistan. But it is just as  likely, if not more so, that Rahman has come to believe firmly that the freedom  he seeks is only attainable by outright independence. His speech last Sunday  would suggest an effort to achieve his goal by gradual assertion of power  without risking a direct confrontation with the army that might follow a  unilateral declaration of independence.
