ERIC: THANK YOU FOR JOINING YOU

I'M ERIC SHAWN.

IT WAS CELEBRATION THAT TURNED

INTO HORRIFIC SLAUGHTER LAST

NIGHT IN KABUL.

162 PEOPLE KILLED, 182 INJURED

AS PRESIDENT TRUMP RETURNS TO

THE WHITE HOUSE AFTER MEETING

THIS WEEK WITH HIS TOP NATIONAL

SECURITY ADVISORS AND CABINET

OFFICIALS OVER POTENTIAL PEACE

TALKS WITH THE TALIBAN A

RESULTING DEAL COULD LEAD TO

FINAL EXIT OF OUR TROOPS IN THE

COUNTRY AND END TO AMERICA'S

LONGEST RUNNING WAR.

THIS MORNING REPUBLICAN SENATOR

LINDSEY GRAHAM TALKED ABOUT ON

"SUNDAY MORNING FUTURES" LEAVING

THAT COULD RESUME REPEATED

ATTACKS ON THE HOMELAND.

>> WE CAN'T LEAVE AFGHANISTAN

WITHOUT COUNTERTERRORISM FORCE

OR INTEL CAPABILITY TO PROTECT

US A AGAINST A 9/11 BECAUSE

AL QAEDA AND IS ISIS IS LIVE IN

AFGHANISTAN.

REPORTER: ISIS CLAIMING

RESPONSIBILITY FOR THAT ATTACK.

A FEW HOURS AGO THE GROUP

POSTING A PROPAGANDA PHOTO OF

THE MAN THEY CLAIM WAS

PERPETRATOR.

TERRORISM EXPERTS SAY THIS MOVE

HAS BECOME A SIGNATURE FOR THE

TERRORIST GROUP WHO USE

AFTERMATH OF ATTACKS TO SPREAD

HATE FAR AND WIDE ACROSS THE

INTERNET.

ONE GUEST AT THE WEDDING

OVERNIGHT WHERE THE ATTACK

UNFOLDED DESCRIBED THE SCENE.

TAKE A LISTEN.

>> Translator: AROUND 1200

GUESTS WERE INVITED TO THE

WEDDING.

I WAS WITH THE GROOM IN THE

OTHER ROOM WHEN WE HEARD THE

BLAST.

THEN I COULDN'T FIND EVERYONE.

EVERYONE WAS LAYING ALL AROUND

THE HALL.

REPORTER: PRESIDENT TRUMP

CONVENED A MEETING WITH THE

NATIONAL SECURITY TEAM THIS

WEEKEND TO FIGURE OUT WHETHER

CUTTING A DEAL WITH THE AFGHAN

TALIBAN IN EXCHANGE FOR

WITHDRAWING U.S. TROOPS FROM THE

COUNTRY MAKES STRATEGIC SENSE.

AFGHAN'S PRESIDENT IS MAKING THE

CASE THE TALIBAN ISN'T TO BE

TRUSTED.

THE TALIBAN CAN'T ABSOLVE

THEMSELVES OF RESPONSIBILITY

BECAUSE THEY PROVIDE A PLATFORM

FOR TERRORISTS.

EVEN SOME OF PRESIDENT TRUMP'S

STRONGEST SUPPORTERS IN THE

SENATE ARE OPPOSED TO A IDEA OF

A DRAWDOWN.

SENATOR LINDSEY GRAHAM TWEETED,

TO TRUST THE TALIBAN TO CONTROL

AL QAEDA, ISIS, OTHER RADICAL

ISLAMIST GROUPS PRESENT IN

AFGHANISTAN AS REPLACEMENT FOR

U.S. COUNTERTERRORISM FORCE

WOULD BE A BIGGER MISTAKE THAN

OBAMA'S IRAN NUCLEAR DEAL.

MILITARY BRASS WHO SUPPORT

WITHDRAWING FROM AFGHANISTAN

MAKE THE CASE THAT U.S. TROOPS

ON THE GROUND HAVE BEEN REDUCED

TO SERVING AS A GLORIFIED POLICE

FORCE.

THEY SAY AFTER 18 YEARS OF WAR,
