1.  A certain (limited) reinforcement of American and Israeli forces has taken place in Azerbaijan. Neither Washington nor Jerusalem has ever acknowledged a military presence in this country that borders on Iran, but Western intelligence sources say that both keep a wary eye on the goings-on inside Iran from electronic surveillance bases in that country.

2.  Iran feels moved to respond to certain US steps: The arrival of the USS Harry S. Truman Strike Group in the Persian Gulf and the Arabian Sea and its war games with France and Israel, which included live-fire bombing practices against targets in Iran.

3.   The execution of Abdolmalek Rigi, head of the Sunni Baluchi rebel organization (including the Iranian Baluchis), on June 20 was intended as a deterrent for Iran's other minorities. Instead, they are more restive than ever. Several Azeri breakaway movements operate in Iranian Azerbaijan in combination with their brethren across the border. Tehran decided a substantial buildup in the province would serve as a timely measure against possible upheavals.
