You are not in the political thread.
You need to start taking Gemara lessons.
You should also see what goes on in a court of law. (I know we're not talking about law here, but about what's right).
Now if one is legally allowed to back out of a commitment, and then takes the step to contact the counterparty and discuss whether he would back out or not (something that is more likely to occur with someone that has less life experience), is that wrong?
