had essentially shut down a vetting process that can take over a year to complete...we don't just have "Open Borders" ;-)...so he and his team were able to accelerate the process and work with other nations, who also need to 'vet' new immigrants, to have them take Afghanis as well...this takes TIME...and Biden, to his credit used as much as he could until Al-Qaeda and ISIS started making things very dangerous (remember the bombing at the airport in Kabul?).
Donald Trump had ZERO PLANS to get those people out of the country...like interpreters who saved American servicemen/women's lives (check out recent story of one Marine Major who got his interpreter and family out)...Trump did had no empathy or appreciation for them...at all..never once did he utter a word about aiding those who wanted to leave....frankly, I don't recall him saying anything about plans to remove American civilians either...do you?
Getting the Afghanis and American civilians out was the whole and sole purpose of extending the exit date from May 1 to the end of August...and Biden got over 120,000 Afghanis and all but a few hundred American civilians (who couldn't make a final decision) out, versus ZERO if he stuck with Trump's "Plan".
Given that hand, Biden did a 'remarkably good' job.
