Most people don't know why they're happy, but there are people who understand what is going on, and the families and victims of all of this ARE getting a lot of closure. Nothing will ever change what happened, but this was a huge step for them.
Can you not see that? It's not about the millions of ignorant American's celebrating for the wrong reasons, it's about for the one's who actually matter.
This is NOT a political victory, this is a human rights victory.
