Shooting at Holocaust Musuem in DC

I know this is not Israel related directly, but I just heard there was a shooting today at the US Holocaust Memorial Musuem in DC and a security guard was killed. This is so shocking. To think that one man who is an Anti-Semite at 88 years old could do this. Could this have repurcussions on the peace issues in the Middle East and how Israel will be viewed? Is this a new era in the US and what may or may not end of being support for Israel and Jews all over the world? Just thought I had to share.
