Probably not so much in Iraq. The people were pretty much left to fend for themselves; before and after 'sanctions.' As an aside, not so much to you, but the Oil for Food corruption hurt the ordinary people in ways that the sanctions never could have, and may have led to the current conflict.
So wait, are you saying that plugging whatever "leaks" were in the blockade would have been good for the Iraqi people?

The only thing that led to the current conflict was our government using flimsy evidence.
Maybe in your strictly libertarina world, but that option for the US has been gone since 1945, to the degree you are wishing for.
It isn't gone at all. That's just empty rhetoric we all learn from grade school history books, along with such rubbish as "FDR got us out of the depression". There isn't any nation on earth that could even come close to matching our military might, and we're surrounded by thousands of miles of ocean. There is no need to intervene in every little pissant conflict all over the globe, and have military bases in 100+ countries.
In 1939 at least you could make a case that Japan or Germany had the means and/or a motive to attack america, especially since we weren't interested in neutrality at that time. However not every situation is "OMG 1938 all over again". The very idea of Saddam being able to send troops across the seas and set foot in america is utterly hilarious. If he conquered the entire middle east (lol), he would not have the industrial base of Germany or Japan in 1939.
He also would not have armed forces that are competent, seeing as how Arab armies are such a joke. Their very culture is notorious for information hoarding, where the left hand doesn't know what the right hand is doing, so to speak. A reporter once asked an Israeli general, What's the secret to the IDF's repeated success against overwhelming (numerical) odds? "Always fight against arab armies" the general replied.
So then you're down to Saddam's funding of the 9/11 terrorists, which didn't happen; or some wacky thing about Saddam using drones to deliver poison gas, which also wasn't true.
BTW, it's "Libertopia".
As OKC and 9/11 proved, one doesn't need WMD to cause mass murder. Terrorizing on a smaller scale-even just 'threats', with the subsequent loss to the economy and well being of the citizens is even easier. It is the #1 job of the government to address such threats from sources that have a proven record of using such tactics-Hamas/Hizbollah come to mind.
It's their job, if that particular group is plotting on attacking america, or it's members are setting foot in america. Otherwise it's none of our concern. I couldn't care less if the Tibetian People's Liberation Front bombs a Chinese city for whatever reason.
Disagree. If a nation poses a threat or attacks a nation or nations allied to the US by treaty, it is considered an attack on the US itself. That in itself is legal justification.
Morally I consider your statement the absolute in selfishness and completely unacceptable, IMO.
I guess nearly every other nation in the world is "selfish" too, for not wanting to get involved in some war that does not concern them in any way.
"Threat to the US" and "WMDs" has been redefined as ICBMs with nuclear warheads. Any other form of threat and/or WMD is discounted since it is not split-second "immediate," for the purpose of making dishonest, one-sided arguments against the current administration.
By evidence I can only assume you mean that with the aid of a crystal ball, we are supposed to somehow nab a perpetrator between the time he takes possession of a WMD and when he uses it. The reality of that type thinking is the US will only be able to react after the fact. I'm sure that brings consolation to the victims.
A perfect "for instance" would be the 9/11 hijackers. Let's just suppose we had pulled our arrogant heads out of our collective "it can't happen to us" trance and paid attention to every little clue and nabbed those nimrods before they acted.
The ACLU, left and MSM would have had a field day making accusations of civil rights abuses against Bush and/or his administration. The evidence of 3,000+ bodies was required. That's a BS way to think and it sets us to lose.
I was under the impression that we did in fact have pretty decent evidence of something fishy with the 9/11 attackers, and that we could have brought them in rather easily. At any rate, 9/11 could have been entirely prevented if we'd allow airlines to profile and/or refuse service based on ethnicity, and simply allow the pilots to carry guns (which the allegedly pro-gun/pro-security Bush administration continues to fight).
I'm afraid that yes, we will have to wait until a government hands WMD's over to terrorists. Otherwise, we're occupying the whole freaking world (which would spread us too thin and weaken us, just like other empires in history that overextended themselves), because any dumbass with a knowledge of chemistry can improvise explosives or poison gas.
I have NO problem with doing so.
Then by all means, find some like-minded individuals, load up your gear, and go on a holy crusade for democracy and freedom in a country that has never known it, and has a culture that would never support it. Just don't ask for the massive taxes and conscription that your crusade would require.
Also, your attitude is unamerican, historically speaking. People came over by the boatload, partially to escape the senseless wars of europe. That's why WWI was so unpopular, the memories of european wars were still fresh in many americans minds. The idea of using force to spread goodness and enlightenment to people who don't threaten us is an idea that was hatched by yankee progressives. Unfortunately, it's infected the rest of the country by now.
