why is american homeland security officials worry more about biological weapons than chemicals an nuclear?

Answer 1

Because biological weapons are about as easy to get as chemical weapons -- and both of those are much easier to get than nuclear weapons.

However, of the two, biological are more a general risk than chemical for two reasons. First, biological weapons are often self-replicating, so only a small amount is needed, and more can be produced from that.

Second, biological weapons are often self-propagating, meaning a larger section of the populace can be harmed from the same initial dispersion.

So, of the three, biological weapons are among the easiest to get and produce, and the easiest to distribute on a large scale.

Answer 2

DONOT BELIEV ,IT IS NONSENSE

I think the present government is bad
let s think fairly
first,do we have the right to have nuclear weapons and others not ?you may say we are a democratic country but you must know that Ahamadi Nejad elected and choosed by the iranian people(NB we are not sure if the president Bush desereved to be a president or not ,do you remeber the votes of the last state)
second: we are a democratic country but we hit Japan with 2 nuclear bombs at the end of the war without the need to do this (Japan was going to surrender)and we donot know if any japanese generation in the future may take revenege or not.
third:we allow some other countries to have nuclear weapond and help them like INDIA and ISRAEL WHICH is dangerous on the world peace and flaming wars from time to time (it is a reason of the hatred of many nations to usa)
forth:we have a very bad foreign policy against many countries like Cuba,Venezuela,middle east,north korea.,do you think if we have a fair normal diplomatic relation with these countries including iran ,does anyone of the world would attack us ?look at Canada ,it has a good realtions with all nations ,there is no terrorrism against it
fifth:we always attack others which makes them going to the steps of revenge.so if we stop shaking Iran regime ,do you think iranians and they know well that we are the strong power ,may attack us??

sixth: dealing with the iraq was is the worst .prisons of Abou ghareb ,killing citizens ,and many things which make others plans for revenge.

at the time of the second world war ,all countries of world and nations was looking up to USA ,now with the wrong decisions ,supporting some dictators,bad forign relations with many countries .the situation is difficult and there must be a change in the US policy

Answer 3

If they talked up the chemical and nuclear dangers, people would find out how woefully inadequate security is at these facilities, it would cost too much and cut down on bonuses for Homeland Security bureaucrats.

Answer 4

Biological agents can be spread over large areas, they are spread by people not being aware they are infected, they travel away from the epicenter and spread to others, who turn spread it more. A chemical weapon (which is very hard to pull off), effects only the people in the general area. Nuclear or dirty bombs, actually are the least effective of all, most people exposed would suffer no ill effects.

Answer 5

mainly because nuclear weapons are very high tech and difficult to create, while you can make biological and chemical agents in your garage. plus, it scares the public less.

Answer 6

Easier to obtain biological weapons.

Though I haven't seen anything that would say it is a higher threat than others.

Answer 7

biologicals have the best potential for the most damage and can cover more of the populace. both would be devastating.
