Washington — Terrorism emanating from the Middle East is beginning to move beyond the control of even those states that have traditionally supported the myriad extremist factions operating both in and outside the region. Groups such as Hizbullah (``Party of God''), the umbrella Shiite Muslim movement in Lebanon of which Islamic Jihad is believed to be a part, are increasingly acting on their own initiative. This trend, which has been emerging in the past year, often runs contrary to the wishes of states such as Iran and Syria that have helped create and support the groups.
But Iran and, perhaps to a lesser degree, Syria retain influence over the extremist groups and are now trying to reassert their control. This jockeying for power may well be a contributing factor in this week's release of American hostage David Jacobsen.
Iran's apparent involvement in convincing Islamic Jihad (``Holy War'') to free Mr. Jacobsen may have flowed in part from Tehran's self-interest. At least one faction of Iranians have something to gain domestically - and in the region - by reining in the extremists at a crucial juncture. There also appears to have been a more specific quid pro quo in what White House chief of staff Donald Regan conceded over the weekend was ``a deal'' with unspecified parties.
Iran's sponsorship of terrorism and misadventures by Muslim extremists now appear to be a key element in the rivalry between moderates and radicals over the future leadership of that country.
At stake ultimately is Iran's reputation abroad, particularly at a time of economic trouble, and its entire approach toward foreign policy and the six-year-old war with Iraq. The current dispute in Tehran is not likely to settle the issue of Iran's future direction. But it may establish a different framework.
The power struggle is reflected in a recent controversy centered on the Islamic Liberation Movement (ILM) headed by Mehdi Hashemi. He is son-in-law and aide to Ayatollah Hossein Ali Montazeri, who, a year ago, was chosen to be Ayatollah Khomeini's successor.
The ILM oversees foreign extremist groups from Lebanon, Iraq, Kuwait, Saudi Arabia, and elsewhere, based in Tehran and involved in ``exporting the revolution'' or undermining Western influence and moderate regimes in the Middle East.
Mr. Hashemi and several of his ILM colleagues were arrested last month on charges of murder, both before and after Iran's 1979 revolution; illegal possession of weapons and secret government documents; forging official papers; and secret illegal activities. Hashemi was also reportedly linked with last month's kidnapping in Tehran of a diplomat from Syria, Iran's closest Arab ally, and with smuggling guns on a Saudi airliner during the annual Muslim pilgrimage in August.
The charges are among the most damning indictments ever against a high-level government insider, particularly one so close to Ayatollah Khomeini's successor.
The case offers an indication of how key figures in the extremist campaign are now considered to have gone beyond what is acceptable to Iran's leadership. It also demonstrates how far the government is prepared to go to stop that. The Iranian theocracy rarely launders its dirty works with such publicity. This development is all the more interesting in light of Jacobsen's release and suggestions that other Americans may be freed.
Iran seems to be reining in the extremists, at home and in the region, and trying to tone down its image as a terror master.
The initiative for Hashemi's arrest apparently came from the emerging moderate block in the Iranian hierarchy, which seeks to change both Iran's policy and the leadership succession. For more than two years, the moderates have struggled to improve relations with Arab moderates and Western nations for political, economic, and military reasons.
Politically, the moderates have long been concerned about breaking out of the isolation enforced by the outside world, which has often held Tehran culpable for various terrorist acts. Radical elements that have supported ILM practices feel that extremist acts are the most effective way to undermine rivals and promote militant Islam. But many moderates argue that the Islamic revival is best served by proving Iran a model state that others will voluntarily want to imitate.
One early indication of the moderates' new approach came during the intervention of parliamentary Speaker Hashemi Rafsanjani during the hijacking of a Trans World Airlines plane in June 1985. Mr. Rafsanjani played a pivotal role, which the US acknowledged, by exerting influence on Hizbullah, to gain the release of 39 US passengers. Iran's moderates have also tried to strengthen relations with some Persian Gulf countries, including longstanding rival Saudi Arabia.
Economically, Iran is unable to even meet its oil quota, set by the Organization of Petroleum Exporting Countries, of 2.3 million barrels per day, according to the Paris-based Petrostrategies Weekly. Due largely to Iraqi air attacks on its oil installations and on ships in the Gulf, Iran's output is only 1.3 million b.p.d., meaning a loss of at least $1.5 billion annually.
Indeed, for the first time since 1979, Iran has rationed petroleum at home. Lost foreign revenue has, in turn, deeply affected Tehran's costly war effort.
Militarily, Iran is concerned by Iraq's Western backing and supply lines, notably from France and the US. The US had no relations with either side when the war began in 1980. But in 1984, Washington and Baghdad established links after a 17-year rupture. Whether or not it is true, Iran believes the US provides satellite intelligence to Iraq on Iranian troop and equipment concentrations.
Iran's alleged involvement with terrorism may be the most important obstacle to solving its major problems, as dealing with Tehran is politically anathema to states that suspect they have been its victim. But changing this situation has been made more complex for Iranian moderates by the increasing independence of various extremists cells, especially those outside the country.
Many groups have been trained in Iran and given weapons or funds. But a growing number of their activities suit their own agendas. They apparently still accept Ayatollah Khomeini as their spiritual guide, but not neccessarily all the political dictates of Iranian officials.
The emergence of at least one new group in Lebanon, the Revolutionary Justice Organization, may be one example. It has claimed responsibility for kidnapping two Americans in the past two months. Reports in Beirut indicate it is another pro-Iranian Shiite group, a factor that could hinder efforts to free all six remaining Americans, since communication has only been established with Islamic Jihad.
In Tehran, the outcome of the Hashemi-ILM case could have a broad impact at several levels. Most important, it could affect Iran's domestic leadership dispute - specifically whether the moderate block or Ayatollah Montazeri and his supporters will guide Iran's future.
And on the terrorism issue, it could decide the limits on activities by extremist movements based in Tehran as well as on their local sponsors. It could also send a signal to groups outside Iran about the range and targets of their campaign.
So far, Ayatollah Khomeini seems to be siding with the moderates, at least on the Hashemi case. In a letter broadcast on Radio Tehran last week, he said the evidence ``produced clear proof that their line has deviated from the revolution and from Islam.'' And he urged prosecution of ``all the accused individuals....''
