Here's how the right wing lizard brain works.
1) US troops suffer a suicide bombing while trying to pull out of Afghanistan that cost 13 American lives and injured others out of 2500 troops then in country.
2) Since the bombing happened, it's the fault of the President who gave the orders. And it's also articulated that the said President was obviously derelict in his responsibility to protect American troops during any military action, as though the troops never knew what was coming at them.
3) Continue to drive the political narrative calling the President reckless and personally responsible for the deaths by bringing grieving families into the political process for your own benefit.
4) Refuse to even consider any actual facts and chronologies of the events leading up to said bombing, showing that the President and military did all due diligence in their planning - including worst case/emergency scenarios - but it simply wasn't enough this time.
And the most revealing fact that the Administration's and military's plans were more sound than questionable is that all the other troops out of the 2500 left in country were safely returned home!
It's tragic to lose any Americans to war. But a known bomber - freshly released from prison after the Taliban overran the allied government that simply fled from the inevitable - succeeded our best efforts to stop him in a massive hoard of desperate Afghanis trying to flee the Taliban. All of this happened as the end result of an agreement entered into by the former President effectively tying his successor's hands and limiting his options, where every single one ends in the Taliban re-engaging attacks on American troops unless we leave the country.
And then that President has the audacity and lack of character to politically place full blame upon his successor in a wholly mendacious manner, insinuating the bombing should have been stopped, without offering a shred of detail as to how that could have been done under the then-existent circumstances.
