@michael_martinez again, the Taliban broke Trump's agreement by acting against Americans.
So there was no longer an agreement on the table. Biden was not honoring Trump's agreement because the agreement had already been broken.
Biden acted on his own. He bears responsibility for his own actions regardless of the agreement, and further, despite the agreement. He cannot blame the agreement for multiple reasons.
And it's not that Biden kept Trump's policies in place, racist or not. The way the US government works every single thing that happens since inauguration day was Biden's policy. Every single thing the US government does right now is under the authority of Biden.
I'm emphasizing this for a particular reason: each president needs to be held accountable for what they do, and they should not be allowed to act as if they passively maintained somebody else's policies. No, it's important to stress the way the US government works, each President is responsible for what happens in their administration, they are active participants in everything that happens.
From inauguration day on these were no longer Trump's policies but Biden's policies. At the most we can say that Biden continued to implement policies similar to Trump's.
But he has to own that, whether a person likes the policies or not.
