Okay let's use a specific example:

I decide that I don't want to trade with Country A because they are producing weapons that they plan on using to attack me with. Now let's say Country B is trading with Country A, and I think they are trading components being used to produce the weapons in Country A.

Is it a violation of Country B's autonomy for me to decide to not to trade with them because they are trading with country A?

If I believe that anyone who trades with Country A is supplying them resources to build weapons to attack me, and I decide to not trade with any Country who is trading with Country A, am I violating the autonomy for all of those countries?
