US President Donald Trump waves as walks on the South Lawn of the White House upon his return to Washington, from the G20 Summit in Hamburg, July 8, 2017.

:: US President Donald Trump assembled his national security team at the Camp David presidential retreat on Friday to forge a way ahead in Afghanistan, almost 16 years after the war began.

Trump must decide if he wants to continue on the current course, which relies on a relatively small US-led NATO force to help Afghan partners push back the Taliban, or try a new tack such as adding more forces – or even withdrawing altogether.

The White House released a statement Friday afternoon saying Trump had been briefed by his national security team on “a new strategy to protect America’s interests in South Asia” – indicating that no decision had yet been reached.

“The president is studying and considering his options and will make an announcement to the American people, to our allies and partners, and to the world at the appropriate time,” press secretary Sarah Huckabee Sanders said.

Defense Secretary Jim Mattis had initially promised to provide a new plan for Afghanistan by mid-July.

But Trump appears dissatisfied by initial proposals to add a few thousand more troops, and the strategy has been expanded to include the broader South Asia region, notably Pakistan advertisement

We are “coming very close to a decision, and I anticipate it in the very near future,” Mattis told reporters Thursday.

Trump’s generals have called the Afghan conflict a stalemate, and even after years of intensive help from NATO, Afghanistan’s security forces still are struggling to hold back an emboldened Taliban.

In an early move to address the situation, Trump gave Mattis broad powers to set troop numbers in Afghanistan and elsewhere.

But several months later, the level remains stuck at about 8,400 US and about 5,000 NATO troops.

Meanwhile the situation is as deadly as ever, with more than 2,500 Afghan police and troops killed between Jan 1 and May 8, continuing a deadly trend from previous years.
