U.S. President Donald Trump in a top meeting with his national security team on Friday postponed taking decision about the 16-year-old war in Afghanistan.

The high-level meeting was held at Camp David to discuss the Afghanistan war strategy with his high-level aides, but the meeting reached nothing.

High profile security team members including U.S. Defense Secretary James Mattis, Secretary of State Rex Tillerson, Director of CIA Mike Pompeo and National Security Advisor H.R. McMaster had attended the meeting to choose an option regarding Afghanistan war.

Due to the importance of the meeting, U.S. Vice President Pence delayed his trip to South America to attend the meeting and to give a hand in finding a solution to the long-Afghan war.

The meeting ended with no solution while on Friday Mattis had told reporters that they will make a decision.

This is not the first time that officials expected Trump to pick up an option regarding the new U.S.strategy in Afghanistan. In May, prior to the NATO summit in Belgium, Trump was expected to make a decision, but a final decision was not made.

Mattis however later in June promised lawmakers that the administration will take a decision sometimes in July, and once again the decision was not made. 

A defense policy expert at the Heritage Foundation, James Carafano, who was also a member of the Trump transition team, said there are a variety of reasons why Trump cannot make a final decision which include the complexity of the war, Trump’s hesitation in making the decision as he afraid that he may choose a wrong path. 

“We need a strategy that’s going to be sustainable maybe eight years. There is no short answer here,” said Carafano, who was a member of the Trump transition team.“The burden really is on the national security team to show Trump they have the most effective strategy to do that, because this is then going to be his war, his responsibility.”

Members of the administration still hold disagreements on the best path forward for Afghanistan, which will include how to handle conflicts along the border of Pakistan. U.S. military commanders earlier had requested more troops in to battle the insurgents, while according to reports, Trump has been very cautious regarding U.S. presence in Afghanistan. 

Mattis and Lt.Gen. HR McMaster want to send 3,000 to 5,000 additional troops to Afghanistan to fight the Taliban, but recently ousted chief strategist Stephen Bannon however said he is against sending more troops.
