You've made a strategic decision, and you acknowledge that you're responsible for it. That's great; it's a big step.
That decision was made by a group of people. You don't know who they are, you don't know how many people were in that group, and you don't know how the decision was made. And yet you claim to be responsible for that decision.
You'll agree with me that you have a strange definition of responsibility.
Is that correct?
