Another good illustration:
In the past 20 years total, deer have killed more on American soil (~150-200/yr) than terrorists.
So where is the trillion dollar War on Bambi?
That's a ridiculous comment. The commentor is comparing the numbers of deaths that occurred over 20 years to the number of deaths that occurred during a single morning on 9/11?
Major terrorist attacks are extremely rare in America. They were rare before 9/11 and they have been rare since. Deer hits, on the other hand, are common and cause extensive damage to vehicles and injuries to drivers.
Also, there is a war on deer, but we prefer to call it "hunting." Hunting regulations are designed to cull the deer population, particularly in areas where natural predators were killed off by humans long ago. Hunting regulations balance the need to keep the deer population down with the need to not drive deer into extinction. It might make sense to bump up the number of kills allowed per hunter per season or to make the seasons longer if automobile hits are a serious enough problem (there are still more deer now in many eastern states than there were when the colonies were first established).
Around where I live if there were not enough deer killed in the regular hunting season, the DNR will open a late season to bring the numbers in line with conservation figures. Deer population conservation is a highly regulated and very important activity since there are so many humans living in areas where deer congregate, and we have been incredibly effective in wiping out their natural predators.
