I've always be told that karate ni sente nashi means there is no first attack in karate, which always seemed a bit strange to me. Now I've just finished watching Jesse Enkamps Karate Nerd in Okinawa on YouTube and at the start of episode 6 he comments on this (starts at 1:25). He translates it as there is no first attack against karate. Now this makes a lot more sense to me, as he says there will be times when you may need to strike first to defend yourself and your loved ones. Does this alternative interpretation/translation make sense to you or is he wrong in what he's saying?
