His comments, which add to growing signs of improved relations between Islamabad and Washington, come amid efforts to press on with talks between the Taliban and the United States aimed at an agreement to end 17 years of war in Afghanistan.
“I’ve seen things change here and all in a positive direction,” Graham, a member of the Senate Armed Services Committee who has generally been a staunch supporter of Trump, told a news conference in Islamabad.
He said that a meeting with Khan, who has declared strong support for a peace agreement in Afghanistan, would leave Trump “far more enthusiastic about the region than he is today”.
“With Prime Minister Khan we have a unique opportunity to change our relationship,” he said. A previously transactional relationship, based on rewards for services rendered, should be replaced by “strategic engagement”, including a free trade agreement, he said.
Trump, who has in the past argued for the United States to withdraw from Afghanistan, has made it clear he wants to see a peace accord reached rapidly although the Taliban have so far refused to talk directly with the Afghan government.
Graham’s trip to Pakistan coincided with a visit by Zalmay Khalilzad, the US special envoy for peace in Afghanistan, and top military commanders including General Joseph Votel, commander of US Central Command.
Khalilzad left Islamabad without announcing a new date for talks with Taliban representatives, who have refused further meetings until the US side agrees to discuss a timetable for withdrawing its forces.
The uncertainty has been increased by reports that Trump is prepared to order more than 5,000 US troops out of Afghanistan, a move that would represent a sharp change in course from Washington’s previous policy of stepping up military action against the Taliban.
With Afghan forces suffering thousands of casualties a year and struggling to hold back the Taliban insurgency, the reports have caused alarm in Kabul, prompting many close to the government to question the US commitment to Afghanistan.
Asked whether there had been confusion over the US message, Graham, who has called for a Senate hearing on Trump’s plans to withdraw US troops from Syria and Afghanistan, said “without a doubt” but added that he did not believe Washington would stand by and allow a Taliban victory.
“The world’s not going to let the Taliban take Afghanistan over by force of arms. That would be unconscionable,” he said. “Any president who let that happen would go down in history very poorly.”
