A number of U.S. Republican senators have expressed their concerns over Afghan war, saying that the situation in Afghanistan will turn ten times worse than Iraq if the country is not considered seriously by the Trump administration.

In a chat with reporters on Thursday, Senator Lindsey Graham said he expects Trump administration to change its strategy in fighting the Taliban in Afghanistan or will face failure.

“We need more troops, General Nicholson I think has done a fine job from my point of view, but President Trump is going to make a decision and he will own it,” Graham said. “If you do not add capability to the fight, is going to get worse not better. What you saw in Iraq is going to happen in Afghanistan tenfold. It’s a place now where an international terrorism is on the rise. ISIL (Daesh) has a foothold we're trying to dislodge them.”

American well-known senator, John McCain in a statement reacted over possibility of dismissal of Gen. John Nicholson, U.S. forces commander in Afghanistan, and said Nicholson is not responsible for America’s failure in Afghanistan war, but instead U.S former president Barak Obama and U.S. president Donald Trump are responsible for what is happening in Afghanistan. 

The senators’ remark comes after Trump’s remarks over asking top security advisers to provide more information on why after 16 years presence in Afghanistan the war is still ongoing.

During a meeting in July 19, Trump told Defense Secretary James Mattsi and Josef Dunford, Chairman of the Joint Chiefs of Staffs to consider firing General John Nicholson, commander of U.S. force in Afghanistan over not winning the long-lasted war.

The U.S. State Secretary, Heather Nauert, however did not comment on possibility of Nicholson firing, but said Nicholson has served well for years and added that U.S. pay special attention to Afghanistan’s war. 

“General Nicholson is a good man. He has certainly served his country well, and we care a lot about Afghanistan and what happens there, and that will continue to be a focus of ours,” said Nauert.

Reports indicate that U.S. top security officials and other key persons such as senators Graham and McCain want Trump to send in 3,000 to 4,000 new forces to Afghanistan.
