Biden Admin To Leave "Core" Diplomatic Staff + Combat Forces To Protect Them At U.S. Embassy In Kabul???

So, presumably they know something they're not telling us...because this sounds idiotic and like it will be a fucking disaster:

   President Biden has just sent combat forces back into Afghanistan to evacuate American civilians at the embassy and Afghans who have assisted us in the war effort. The 3,000 American forces will then presumably shoot their way out as they depart.
   Inexplicably, we will leave a "core" diplomatic staff and U.S. combat forces to protect them. The Biden administration believes the Taliban will leave these Americans alone, because they want world approval.
   The Biden administration is living in a fantasyland if they think this is going to end well. But when it comes to Afghanistan our political and military leaders have been living in fantasyland for years.
