Reagan reinforces stand on troops in Lebanon

President Reagan said Wednesday US troops will stay in Lebanon - and retaliate when attacked - until all foreign forces leave that ravaged country or the Beirut government suffers a ''complete collapse.''

The President's remarks could add to the pressure on Lebanese President Amin Gemayel, who is striving to keep alive talks on national reconciliation and who is viewed as dependent on Washington.

''We are certainly not going to enter a war,'' he said. But he said, ''We are not going to send our men anywhere where they cannot defend themselves.''
