Yielding to a threat usually fails

“[I]f you yield to a threat, you do so in order to avoid war, and more often than not, you do not avoid war. For those before whom you have thus openly demeaned yourself by yielding, will not stop there, but will seek to extort further concessions, and the less they esteem you the more incensed will they become against you.”

– Niccolo Machiavelli, Discourses Book II, Chapter 14
