Perhaps, but I suspect that having submitted verbally and publicly also lessens one's will to fight later.
This is complicated by the fact that we are living in a time when words have lost their meaning ("Look at me. I did not have sex with that woman," for example...) and lying is assumed to be normal practice. In fact, we can practically assume somebody is lying unless we have absolute proof otherwise. The result is that people don't feel that what they say really matters.
My feeling is that it does, and that sooner or later, we have to decide at what point we simply dig our heels in and refuse to be coerced. That doesn't mean that we're going to necessarily be brave enough to resist when the time comes, but at least we're going to try.
