How long before the US Kristallnacht happens?

As someone who doesn't live in the US, I am seriously concerned about what has been happening over the last 9 (yes just nine) days. I have been worried about the rise of fashism in the US since before Obama, but now it's real. Am I overreacting or are Americans just like the Germans in the 1930s - "It's the 20th century, we're a civilised country, nothing too bad can happen."
