1) It is VERY surprising to see The Taliban roll over that country with such ease.
2) No decision is perfect, but it was the right decision for Biden to pull US troops out of there.
3) It is a tragedy what's going on in Afghanistan, but we can't police the world. Assuming The Taliban takes over the whole country, they WILL have to govern, and successful governing involves dealing with other countries. The US can and will put serious economic restrictions on that new government. That will hurt the people of Afghanistan, but that is not something we can avoid. The people there will ultimately have to rise up if the want change.
