Sure, but that was only a personal opinion tangent and not the core of my argument which still stands. That's like the safari guide telling you to stay in the vehicle because the Bengali tigers outside will maul you and you go "Ackshually, those are Siberian Tigers, not Bengali." While you're technically correct, it doesn't change the point.
Trust isn't a binary. If everybody trusted all of their neighbors as much as South Korea trusts North Korea then the world economy would collapse and we'd likely have billions of deaths.
It isn't binary but clever countries with a strong defense policy like the US and Switzerland also have insurance polices and backup plans for the case their allies turn against them since it's better to be a warrior in a garden than a gardener in a war. Guess in which case Europe is a the moment?
