Trump on Tuesday night in his State of the Union address that the U.S had "liberated virtually all of that territory from the grip of these bloodthirsty killers" and American allies are working to destroy the 'remnants of ISIS'.
Even as Trump and Secretary of State Mike Pompeo defended the withdrawal decision, which shocked US allies and led to the resignations of Defense Secretary Jim Mattis and the USA envoy to the anti-IS coalition, Brett McGurk, some military leaders, renewed their concerns.
President Donald Trump's announcement that U.S. troops would leave Syria caused outrage at home and overseas.
Trump also declared the Islamic State militant group all but defeated, in a departure from his earlier claim that the group had already been eradicated in Syria.
But the president later slowed down the withdrawal after several resignations from key defence officials and strong criticism from Republicans and allies overseas.
The 79-member Global Coalition to Defeat ISIS was formed in 2014 and works to reduce the threat the armed group poses to worldwide security and United States homelands. "The fight is one we'll continue to wage alongside you".
"It simply represents a new stage in an old fight", Pompeo said, adding that although progress has been made in defeating ISIL, the group remained a unsafe threat.
Pompeo said, "To that end, we ask that our coalition partners seriously and rapidly consider requests that will enable our efforts to continue".

U.S. forces withdrew from Iraq in 2011, but returned in 2014 at the invitation of the government to help battle ISIS after it seized vast areas in the north and west of the country, including Iraq's second largest city, Mosul. "Our troops have fought with unmatched valor - and thanks to their bravery, we are now able to pursue a political solution to this long and bloody conflict", he told members of congress during his speech. He quit following the president's troop withdrawal announcement. A US-led coalition provided crucial air support as Iraqi forces regrouped and drove ISIS out in a costly three-year campaign. "We've beaten them and we've beaten them badly". He also reaffirmed his determination to pull out roughly 2,000 United States troops from Syria. "Great nations do not fight endless wars", Trump told Congress.
Iraqi officials have criticized Trump's comments, saying that the U.S. was in Iraq at the invitation of Baghdad and that its military presence should not be used against Iran.
Gen. Joseph Votel, the head of Central Command, made the assertion in a written statement to the Senate Armed Services Committee.
"The coalition's hard-won battlefield gains can only be secured by maintaining a vigilant offensive against a now largely dispersed and disaggregated ISIS that retains leaders, fighters, facilitators, resources and the profane ideology that fuels their efforts", he added.
A Defense Department Inspector General report published Monday said that "absent sustained [counterterrorism] pressure, ISIS could likely resurge in Syria within six to twelve months and regain limited territory".
