People who remember the Gulf War tend to say that markets finished it at much the same level as when it started. That is true, but it misses a few relevant points. First, the West won that war relatively easily but markets looked pretty sick until the outcome was beyond doubt. Second, though markets came through in good shape, the spike in oil prices provoked a worldwide economic slowdown. Third, stock markets in Europe and America were on much lower earnings multiples and therefore much less vulnerable on the down side at that time than they are now.
