Trump's stunning weekend announcement that he had canceled a secret meeting with Taliban leaders and the Afghan president at Camp David and halted negotiations left many in Washington and Kabul scrambling to understand just what happens now.
"They're dead," Trump said of the negotiations on Monday, after the Taliban signaled they would return to talks.
At the same time, the Taliban said Trump's decision to upend the deal just before its signing "displays lack of composure and experience," and they vowed to continue their fight against "foreign occupation."
"What more violence can they bring?" Afghan presidential spokesman Sediq Sediqqi said in an interview. "What else can they do? You know they have killed 300 civilians in the past three weeks. ... So we will not be surprised if we see more attacks, but they have already done it."
Political analyst Waheed Muzhda was gloomy about the prospects for the country.
Afghans were wary of fresh violence in part because Trump's announcement came shortly before a string of highly sensitive days in Afghanistan, including Monday's anniversary of the killing of anti-Taliban commander Ahmad Shah Massoud, the major Shiite Muslim holy day of Ashoura on Tuesday, and Wednesday's 9/11 anniversary.
There were no immediate reports of any major attacks in the country, but the streets of the capital, Kabul, were largely empty as armed supporters of Massoud, a rare Afghan unifying figure who was killed two days before 9/11, roamed in flag-draped vehicles, firing into the air in a show of power. One police officer was killed, officials said.
Elsewhere in Kabul, a roadside bomb wounded three civilians, but there was no claim of responsibility. And in northeastern Takhar province, the Taliban claimed attacks on at least two districts overnight, with no immediate reports of casualties.
In calling off negotiations, Trump cited a Taliban car bombing Thursday near the U.S. Embassy in Kabul that killed an American service member along with 11 others. The insurgent group has defended its continued attacks even while a deal was taking shape, saying they were intended to strengthen its bargaining position.
Trump's decision got a mixed reaction in Afghanistan.
Many people seek peace above all after four decades of various conflicts. But some fear a failed or weak deal could lead to the government's collapse and bring another civil war like the one that raged in the 1990s before the Taliban swept into power.
Some feared that the deal that was on the table would do little or nothing to stop the carnage against the Afghan people. Also, many Afghan women have been wary of a Taliban return to power in some form under the intra-Afghan talks that would follow a U.S.-Taliban deal, recalling the years of oppression under a strict form of Islamic law.
Under the agreement in principle that the U.S. and the Taliban had worked out, the U.S. would withdraw about 5,000 of the 14,000 American troops in the country within 4½ months, and the insurgents would agree to prevent Afghanistan from being used as a launch pad for global terror attacks by al-Qaida and others.
But such assurances would be "unbelievable," said Sediqqi, the Afghan presidential spokesman. He said other groups across the region would have seen the deal as a victory for the Taliban and "would have joined them."
He said the only way now for the Taliban to re-enter the peace process is to accept a cease-fire and speak directly with the Afghan government, which has been sidelined in the talks because the Taliban dismiss it as a U.S. puppet.
Others in the government of Afghan President Ashraf Ghani reacted positively to Trump's decision.
"Inviting un-repenting & unapologetic terrorists and mass murderers to Camp David would have tarnished the stature of the camp. ... Gratified that US returned back to a principled stand," Ghani's running mate, Amrullah Saleh, tweeted.
Ghani, who is seeking re-election, has been insisting that the country's Sept. 28 election be held as scheduled and not set aside by a U.S.-Taliban deal. Trump's decision appears to have suddenly opened the path to a vote.
The Afghan president appeared to make an important shift in his stance on direct talks with the Taliban, declaring that his country is ready to meet but that "negotiation without a cease-fire is not possible." The Afghan government had previously said it had no conditions for entering talks with the Taliban.
Ghani also invited Taliban chief Maulvi Hibatullah Akhunzada to a video conference and urged him to "at least talk with people" instead of hiding.
