WASHINGTON, Oct. 23 —Senior United States specialists here say that India and the Soviet Union are quietly collaborating to promote the political separation of East Pakistan from the central Pakistani Government and its independence under Indian protection. They report that Moscow is currently cautioning India not to recognize — prematurely the state proclaimed by the East Pakistan separatist movement known as Bangla Desh, lest this lead to an armed clash with the Pakistani Government of President Yahya.

Instead the Soviet Government is said to be counseling India to deploy her armed forces for self‐defense as a warning to Pakistan and above all as a show of support for the Bangla Desh movement.

Meanwhile, according to highly placed informants here Moscow is giving political sup port to India's clandestine assistance to the guerrillas in East Pakistan in arms money and guidance in the expectation of a major political victory for India without the risk of war.

Duo in U. S. Nov. 3

Qualified informants are interpreting the decision of Prune Minister Gandhi to leave India tomorrow for a visit to European capitals and the United States—where she is due Nov. 3 for a five‐day visit —as a sign that India is not likely to attack Pakistan.

“The Indians don't want war. Neither do the Paks,” said one official. “What the Indians want—and what the Russians are urging on them—is an independent East Bengal closely linked with India somewhat like Sikkim or Bhutan.”

Sikkim in the Himalayas north of East Pakistan is protectorate of India which controls her internal and external policies. Bhutan east of Sikkim is legally independent and recently joined the United Nations but has agreed to be guided by Indian views in her foreign policy.

Qualified informants here say that virtually from the be ginning of the civil strife last March India has been steadily increasing her aid in money, arms and military advice to the Bengali rebels.

“The headquarters of the Bangla Desh movement is in Calcutta,” one expert here pointed out. “What's becoming more and more evident is that when the break comes—and it's coming—the Bangla Desh government will move back to Dacca under Indian sponsor ship.”

Mobilization in Northwest

Meanwhile, defense specialists say India has mobilized her armored units in the north west to prevent a Pakistani thrust to seize all Kashmir in case of a clash. In 1965, during the 22‐day Indian‐Pakistani war, most of the fighting took place in the Kashmir area in the extreme northwest and in the Rann of Kutch on the south west Indian‐Pakistani border near Karachi, the main Pakistani port.

Currently, the specialists re port, both India and Pakistan have 250,000 men each mobilized along the Indian‐West Pakistani borders.

In East Pakistan they say, the Pakistani forces total 75, 000 men—although they are not in combat formations. They are being used principally, informants here say, in small scattered detachments as paramilitary constabulary or to combat the Mukti Bahini, the Bangla Desh guerrilla forces.

The Indian forces now reported to encircle East Pakistan are said to number 100,000. Their presence however is felt here to he aimed less at a possible invasion of East Pakistan than at preventing any Chinese countermoves in the Himalayan passes to the north as occurred in 1962.
