Writing on X, Sikorski referred to his own experience of Afghanistan, where Polish forces were deployed as part of NATO-led operations.
He said he had known the country since his youth and had later visited it while serving as both defence and foreign minister, adding that Ghazni province, where the Polish contingent was stationed, was a frontline area with a high level of danger.
"No one has the right to mock the service of our soldiers," he wrote.
His comments came amid growing criticism from Poland and other allies of recent remarks made by President Trump.
In a Fox News interview, he said he was "not sure" NATO allies would support the United States "if we ever needed them" and claimed allied troops in Afghanistan stayed "a little back, a little off the front lines."
Poland’s Prime Minister Donald Tusk also responded, recalling his participation in a farewell ceremony for fallen Polish soldiers in Ghazni in December 2011.
"The American officers who accompanied me then, told me that America would never forget the Polish heroes. Perhaps they will remind President Trump of that fact," he wrote on X.
Tusk’s post was later shared by Tomasz Siemoniak, Poland’s minister responsible for coordinating the security services, who said he had been in Ghazni in 2011 following what he described as "the most tragic day in the history of Poland’s overseas military missions".
He recalled that five Polish soldiers were killed in an attack on 21 December that year, a date later designated as Poland's National Day of Remembrance for Soldiers Fallen in Foreign Missions.
The war in Afghanistan is the only conflict in which NATO’s collective defence clause, Article 5, has been invoked, following the 11 September 2001 attacks on the United States.
In the years that followed, NATO allies deployed forces to Afghanistan and Iraq as part of long-running operations.
Poland’s military involvement in Afghanistan lasted nearly two decades and included more than 33,000 soldiers and defence ministry personnel.
During the mission, 43 Polish soldiers were killed or died, along with one civilian paramedic.
In Iraq, where Polish forces were deployed between 2003 and 2008, more than 15,000 soldiers took part, with 22 killed.
