Entirely incorrect.

As an orthodox Jew, I can tell you that failure to circumcize your son at 8 days old (outside of extenuating circumstances, e.g. medical issues) is one of the worst sins you could commit.

Furthermore, you would be ostracized from the community, and your child will suffer socially, and emotionally.

Once the child turns 13 he is responsible to ensure that he it's circumcised, and considering that he most likely will not have abandoned his religion by 13 he will go through with it. So now there's physical pain as well.
