A Few Things for the Weekend.

First--about Musk's experience with close quarters fights (I am sure he has a lot of experience with those) with knifes. 

Secondly. In Europe he would be ostracized and eventually driven out of any sports. In the US--he is the Captain of the Capital's team and, boy, he has so many people rooting for him. They don't care that he is Russian, they just love them their own big EIGHT. 

That's the difference in scale and destinies, unless, of course, Trump fucks it up, but we have to wait and see.
