They lost Afghanistan. Pretty major loss I'd say. you can even bring yourself for admit it. pretty sad. Just say to yourself, every night, we we in control of Afghanistan, We are now not. We fought for it, we died for it and we lost it. You are not a more patriotic American if you live in a delusion.
Unless it's our objective to annex Afghanistan into our 51st state (No way, as that's the fate for Puerto Rico) we never "Had" Afghanistan. It's a sovereign nation. You cannot lose something you never had. Because we are not staying permanently or having them the same status like American Samoa or Guam, so we will have to leave Afghanistan at some point, be it 20 years or 100 years.
If our objective is to invade and annex Afghanistan, then yes, we "Lost" Afghanistan.
You seem to have problem digesting what or why we were there, we were there to dismantle AQ network in Afghanistan, and then hunt down OBL, and later on into a nation building mission, if you ask me, it is a mistake, we should have better thing to do than to build a nation and leave it at their own device, it only make sense if we are to annex it as part of US territories. But hey, top brass want what top brass want.
On the other hand, leaving the country back with Taliban is probably a smart move, because we know for sure the moment we leave, the Chinese will smack money in front of Ghani face and he will be their "Yes" man, at least it will have no effect if you smack money on Taliban face.
It wasn't Trump's decision it was the US military decision which was endorsed by the politicians who realised they had been defeated. Of course they will try and put a spin on it but the facts tell the true story, just like the Russians are trying to put a spin on the facts in Ukraine.
It's was
SOLELY BECAUSE OF TRUMP...... no one, not even SecDef want to sign Doha Agreement.
Again, the military side of Operation were never defeated, so US military will not unilaterally pull out of Afghanistan, I mean, Taliban didn't even do a "Tet" during those 20 years, that's how incompetent Taliban was.
Military only pull out if there are serious and major defeat on the field, like the Kharkiv Offensive in Ukraine, that's why I ask you to name a COB or FOB that was being overrun by Taliban to be considered a pull out.
