As usual, you try to begin the thread off with innocence as if you were some truth seeker, and then end up making clear inaccurate assertions, based on a few minutes of research; resulting from your own Islamaphobic bias.
1. An Islamic state does not exist.
2. No country today has instituted proper Shariah. Even Saudi try to mix their own constitution in, and many of the rulings are contradictory to Shariah.
Those who think that Saudi Arabia, and the mentioned countries are Islamic States are guilty or reductivism. They qualifications for an Islamic State are conceptual, institutional, procedural and legal. Implementing certain codes from Shariah does not amount to piety in this case, but hypocrisy.
3. Where they have instituted some Aspects of Shariah , you can see the benefit. For example;

Saudi's murder rates (amongst the lowest 10) - http://www.mapsofworld.com/world-top...der-rates.html
The crime rate in Saudi Arabia is very low compared to more industrialized countries. An analysis was done using INTERPOL data for Saudi Arabia. For purpose of comparison, data were drawn for the seven offenses used to compute the United States FBI's index of crime. Index offenses include murder, forcible rape, robbery, aggravated assault, burglary, larceny, and motor vehicle theft. The combined total of these offenses constitutes the Index used for trend calculation purposes. Saudi Arabia will be compared with Japan (country with a low crime rate) and USA (country with a high crime rate). According to the INTERPOL data, for murder, the rate in 2000 was 0.71 per 100,000 population for Saudi Arabia, 1.10 for Japan, and 5.51 for USA. For rape, the rate in 2000 was 0.14 for Saudi Arabia, compared with 1.78 for Japan and 32.05 for USA. For robbery, the rate in 2000 was 0.14 for Saudi Arabia, 4.08 for Japan, and 144.92 for USA. For aggravated assault, the rate in 2000 was 0.12 for Saudi Arabia, 23.78 for Japan, and 323.62 for USA. For burglary, the rate in 2000 was 0.05 for Saudi Arabia, 233.60 for Japan, and 728.42 for USA. The rate of larceny for 2000 was 79.71 for Saudi Arabia, 1401.26 for Japan, and 2475.27 for USA. The rate for motor vehicle theft in 2000 was 76.25 for Saudi Arabia, compared with 44.28 for Japan and 414.17 for USA. The rate for all index offenses combined was 157.12 for Saudi Arabia, compared with 1709.88 for Japan and 4123.97 for USA.
"Crime in Saudi Arabia is relatively low when compared to some developed nations, but may be increasing due to higher levels of foreign workers and higher levels of unemployment among Saudi residents."
— John Wilson, on the crime situation in Saudi Arabia, in the book International Security and the United States: An Encyclopedi
Though I somewhat agree with the above (in terms of crime rising), I think last year Saudi had almost a 70% rise in the number of executions they carried out.
This is not Shariah to blame, but the corruption in implementing it. Saudi's corruption is something many can agree with.
4. Lol @ saying Iran can have Shariah.
5. Common sense, some of the Muslim countries that have banned things such as Alcohol, smoking, drugs etc. based on Shariah, have far less fatalities/problems/injuries caused by such things like you may find in countries that have it legalised.
6. Poverty also has nothing to do with Shariah. A Caliphate would never be living in a mansion or having "billion dollar banks across the globe" like Gaddafi, Ben Ali, Mubarak and so forth have.
I can go on.
It was under Shariah that civilization for the first time could actually thrive. History has proven this again and again (Al Andalus etc.), just like it has in the past, it can also do it today, if applied properly, with a Caliphate.
Has Sharia failed in these regions? Has it been applied wrongly? Or is it just that inherently, Sharia law is not the way to go if you want societies to develop and progress.
The ruin of the empire of the Romans, and, along with it the subversion of all law and order, which happened a few centuries afterwards, produced the entire neglect of that study of the connecting principles of nature, to which leisure and security can alone give occasion. After the fall of those great conquerors and the civilizers of mankind, the empire of the Caliphs seems to have been the first state under which the world enjoyed that degree of tranquility which the cultivation of the sciences requires. It was under the protection of those generous and magnificent princes, that the ancient philosophy and astronomy of the Greeks were restored and established in the East; that tranquility, which their mild, just and religious government diffused over their vast empire, revived the curiosity of mankind, to inquire into the connecting principles of nature.
