Kin of the 13 US troops killed in Afghanistan during President Biden’s disastrous 2021 withdrawal told The Post on Friday they were infuriated – but not surprised – by the disrespect he showed in falsely claiming at Thursday’s debate that no service members died overseas under his watch.

In one of the lowest of his numerous low points during his presidential showdown with Donald Trump, Biden seemingly forgot about the 16 troops who have died in overseas attacks over his tenure in the White House, including the 13 in Kabul on Aug. 26, 2021, and another three in Jordan just five months ago.

“The truth is, I’m the only president this century that doesn’t have any this – this decade, that doesn’t have any troops dying anywhere in the world, like [Trump] did,” Biden said.

While the words shocked many across the nation, the repulsive faux pax particularly stung the hearts of the Gold Star families who lost their loved ones in the violent attacks on US troops since Biden took office in January 2021, said Mark Schmitz, whose son Marine Cpl. Jared Schmitz was among the fallen 13 in Kabul.
