You forget about the probability that they would actually use them,

Hense the reason I said "that Iraq has WMDs AND plans to use them on the US (or some other place)."

I was disregarding all info about them having them and not planning on using them in this calculation.

You seem to have missed 5) Iraq has no WMDs and the invasion of Iraq kills lots of people and makes the use of WMD by a country that also didn't have WMDs more likely.

For obvious reasons it seems a bad plan to miss that possibility.

I hadnt thought of that part of the equation. Would it not be possible that showing our military dominance would make countries that have or dont have WMDs less likely to attack us? Is this not also a possibility? Maybe dominating the Iraqi military would "knock some since" into other enemies.

Dont get me wrong. Im not saying we should have went to war. Actually I think we shouldnt have gone. I just think the left wing liberal media has blown it way out of proportion. And people with out the ability to think on their own just believe what ever CBS or NBC says. Im trying to come up with a mathematical formula that will show it was a much closer "raise/fold" situation than the media leads us to believe. I guess I could just do what the media does and use my calculation with out asking for the flaws in it but we dont need more statisticians we need more stats. "Stats dont lie statisticians do."

Re: Statistics Question (about invading Iraq)
 

IMO your logics is very flawed here.

By your logics: Russia has an arcenal to kill all the people in USA, if USA strike first and destroy all the nuclear bombs in Russia only about 1 millon people in Russia will get killed. After this attack the anti-missile defence will stop what is left with probability of 90%, in 20% cases one missile will get to the USA killing 2 millon people. So if there is 1/250= 0.5% that the russians can launch an attack, then USA should strike first. 0.5% is really small, isn't it?
No wonder that they don't believe all the talk that the target of anti-missile defence is Iran. (Assuming that politicians in USA used a similar logics, when attacking Iraq.)


May be you should take another side into equation, like what Iraq would gain by launching an attack on USA, and what it would lose? Then your 2% estimation becomes HUGE.

Can we avoid the politics here, please?

Re: Statistics Question (about invading Iraq)
 

Your second case is correct, btw. Assuming 100,000 lives will be lost when we go to war, we need to save 500,000 lives in order to justify going to war. But this just jiggles the variables. It's not really a "better way of looking at it." There is no mathematical way to determine whether war is justified - there are too many variables and too many unknowns (and too much subjectivity). The question is political in nature, it's not statistical in nature.

The danger of making gross assumptions and then using math to "justify" a position on that basis is illustrated best by John von Neumann and his claim that the US should have bombed Russia during the Cold War. Despite a probable death toll of millions on both sides, and the potential end of humanity as we know it, he "mathematically" established that we should initiate global war based on considerations similar to your own. Thankfully, nobody listened.

maybe but not including it in your calculation is a very bad and popular mistake.

The trouble with knocking sense into your enemies is that the sensible response to attacking countries without WMDs on the pretext that they have them is for other threatened countries to get WMDs.

I recently calculated how much evidence is needed to make invading Iraq the correct decision (death toll wise). I figured there are 4 possible outcomes.
1)Invasion of Iraq kills 82,000 Iraqi civilians whether they have WMDs or not (2 of the 4 outcomes)
3) Iraq does have WMDs and we dont attack. (assuming they would plan to use them in a very populated area like NYC). Population of NYC is 8,200,000.
4) Iraq doesnt have WMDs and we dont attack. No one dies.

I used the entire population of NYC (which is probably more than will actually get killed by a WMD).

Here is the formula I came up with. Please let me know if you see flaws.

X = % of time that invading Iraq will result in a smaller death toll. I took half the population of NY because if we dont attack and they have WMDs 8.2 million people die, but if they dont have WMDs 0 people die. (8.2+0)/2 =4.1 million

82,000x = 4,100,000 (1-X)
82,000x = 4,100,000-4,100,000x
4,182,000x = 4,100,000
X = .98

So if as little as 2.1% of the evidence gathered it would suggest that invading Iraq will have a smaller death toll than not invading and taking the risk. (Both the 82,000 Iraqi civilians and the population of NY were verified by reliable sources online.)

I am wondering if the math is messed up or I made too many assumptions (I think I used a formula usually used to calculate 2 possible out comes when there are actually 4 possible out comes). Because this number seems really low.

Once again I am looking to make sure that math and formula is right. I know that not everyone in NY would die I just took that number to see if the formula worked. If everything is correct I will figure out a more realistic number.

Any help would be appreciated.

Totally flawed analysis because you assumed if Iraq has WMDs then they automatically will nuke NYC. If you want a fair analysis, you need: Iraq has WMDs but won't use them against the US, for which the probability would be ridiculously high.

Logically, in a democracy the military is only the extension of the political will, and hence when the majority desires war and the order is given the military should follow suit. It is complicated abit by international treatises and european legal doctrines that came with the advent of 'modern' country-country politics: casus belli

And ofcourse the state has to weigh the possibiliy of sanctions, public relations, loss of diplomatic leverage, economical consequences and all these things. But the popular stance that war isn't legitimate, is completely wrong. If war wasn't legitimate then the legitimate people would have a major problem with the illegitimate ones.

Note that this post is not intended as a reflection on the Iraq war specifically, just addressing the issue in general - which is probably healthier because you lose the political dead weight (the Iraq war is a loaded issue and the US is a loaded issue - a 'general' war and an unspecified nation would probably be better to use).

Your analysis sucks, but I'm pretty sure this White House would be pretty happy to hire people like you. Wow, "Math" and everything to prove them right.

Thanks for making such a thought provoking post.

Why dont you try figuring out a better formula? At least I tried to use logic and reasoning to find out my own answer instead of listening to the news. Good luck living your life only believing what others tell you though.
