Nothing will happen soon if you are waiting for Congress to find the answers. This is either setting up an October Surprise™ which sucks huge dicks or it all gets deep-sixed if we don't win the WH and both houses of Congress (like holding a gun to our head to vote Red on another campaign-promise election).
So you have the military and yet you allow foreign funded entities to take over part of a major city and you do nothing about it. But let's make sure the poppy fields in Afghanistan are secure from the Taliban.
>Q: can we prove it?
We don't know. Meanwhile, we can just sit here and continue to watch Americans die while we wait to see what happens. You hold the cards. The ball is in your court.
