Einsatzgruppen

More could have and should have been done to stop the Einsatzgruppen from their terrible deeds.  People who were near Jews and Soviet Union officials should have taken a stand and stopped all of the genocidal murders.  America, the United Kingdom, France, and other Allied powers could have sent in any available troops or supplies that they had.  The people that were being attacked also should have been more prepared.  Instead of turning each other in, victims should have teamed up and defended against the Nazi forces.  The allied powers should have been more aware of what was going on in Europe at that time.  All in all, many horendous attacks could have been stopped or at least slowed down and less people could have died during the Holocaust.
