John McCain said Thursday he'll try to force the debate on Capitol Hill, offering his own plan that would force a troop increase.
Currently, there are about 8,400 United States troops and another 5,000 forces of the North Atlantic Treaty Organisation (NATO) on the ground in Afghanistan to train and assist local forces against extremists, and conduct counter-terrorism missions.
"Imposing graduated diplomatic, military, and economic costs on Pakistan as long as it continues to provide support and sanctuary to terrorist and insurgent groups, including the Taliban and the Haqqani Network", said the McCain strategy on Afghanistan.
President Donald Trump said Thursday he was "very close" to revealing his keenly awaited decision on the number of U.S. troops he plans to keep in Afghanistan.
"I took over a mess, and we're going to make it a lot less messy". It's a very big decision for me. "They were the right questions that he should be asking, and perhaps these are questions that no one's been willing to raise in the past", Secretary of State Rex W. Tillerson told reporters earlier this week.
The New York Times reported earlier Friday that Afghan officials said USA aircraft killed 16 civilians as they tried to flee the area.
His plan calls for sending in more US combat forces, although he doesn't say how many.
President Trump also commented that he doesn't want to listen to his military leaders any more, because they give "lousy" advice.
"America is adrift in Afghanistan", he said. President Obama's "don't lose" strategy has put the U.S. on a path to achieving the opposite result, McCain said.
"Nearly seven months into President Trump's administration, we've had no strategy at all as conditions on the ground have steadily worsened", said Mr McCain, the Republican chairman of the senate armed services committee and a leading voice in congress on national security matters. "The thousands of Americans putting their lives on the line in Afghanistan deserve better from their commander-in-chief".
The State Department said the US' Afghan policy review is still under way.
The Pentagon is disputing reports that numerous civilians were killed in an eastern Afghanistan airstrike on Islamic State in Iraq and Syria militants.
It appears McCain has made good on that promise a little earlier than expected with a new amendment Thursday to the National Defense Authorization Act that lays out the need for a long-term presence in Afghanistan by increasing USA counter-terrorism forces and US air power.
The victims died Thursday afternoon when the vehicles they were traveling in were hit by USA air strikes believed to be targeting Islamic State militants in the area, Wali said.
