Pact of Umar

Please tell me what was the difference in its treatment of Christians in Mosul to the pact of Umar:
The ruler would provide security for the Christian believers who follow the rules of the pact.
Prohibition against building new churches, places of worship, monasteries, monks or a new cell. (Hence it was also forbidden to build new synagogues, although it is known that new synagogues were built after the occupation of the Islam, for example in Jerusalem and Ramle. The law that prohibits to build new synagogues was not new for the Jews, it was applied also during the Byzantines. It was new for the Christians.)
Prohibition against rebuilding destroyed churches, by day or night, in their own neighborhoods or those situated in the quarters of the Muslims.
Prohibition against hanging a cross on the Churches.
Muslims should be allowed to enter Churches (for shelter) in any time, both in day and night.
Obliging the call of prayer by a bell or a kind of Gong (Nakos) to be low in volume.
Prohibition of Christians and Jews against raising their voices at prayer times.
Prohibition against teaching non-Muslim children the Qur'an.
Christians were forbidden to show their religion in public, or to be seen with Christian books or symbols in public, on the roads or in the markets of the Muslims.
Palm Sunday and Easter parades were banned.
Funerals should be conducted quietly.
Prohibition against burying non-Muslim dead near Muslims.
Prohibition against raising a pig next to a Muslims neighbor.
Christian were forbidden to sell Muslims alcoholic beverage.
Christians were forbidden to provide cover or shelter for spies.
Prohibition against telling a lie about Muslims.
Obligation to show deference toward Muslims. If a Muslim wishes to sit, non-Muslim should be rise from his seats and let the Muslim sit.
Prohibition against preaching to Muslims in an attempt to convert them from Islam.
Prohibition against preventing the conversion to Islam of some one who wants to convert.
The appearance of the non-Muslims has to be different from those of the Muslims: Prohibition against wearing Qalansuwa (kind of dome that was used to wear by Bedouin), Bedouin turban (Amamh), Muslims shoes, and Sash to their waists. As to their heads, it was forbidden to comb the hair sidewise as the Muslim custom, and they were forced to cut the hair in the front of the head. Also non-Muslim shall not imitate the Arab-Muslim way of speech nor shall adopt the kunyas (Arabic byname, such as "abu Khattib").
Obligation to identify non-Muslims as such by clipping the heads' forelocks and by always dressing in the same manner, wherever they go, with binding the zunar (a kind of belt) around the waists. Christians to wear blue belts or turbans, Jews to wear yellow belts or turbans, Zoroastrians to wear black belts or turbans, and Samaritans to wear red belts or turbans.
Prohibition against riding animals in the Muslim custom, and prohibition against riding with a saddle.
Prohibition against adopting a Muslim title of honor.
Prohibition against engraving Arabic inscriptions on signet seals.
Prohibition against any possession of weapons.
Non-Muslims must host a Muslim passerby for at least 3 days and feed him.
Non-Muslims prohibited from buying a Muslim prisoner.
Prohibition against taking slaves who have been allotted to Muslims.
Prohibition against non-Muslims to lead, govern or employ Muslims.
If a non-Muslim beats a Muslim, his Dhimmi is removed.
The worship places of non-Muslims must be lower in elevation than the lowest mosque in town.
The houses of non-Muslims must not be taller in elevation than the houses of Muslims.

I see no difference to Isis in Mosul or the actions of so called Islamic extremists to what the original Muslims and Khilafat did.

I didn't ask for a conspiracy theory, Isis is clearly Islamic as you can see I dare you to,sa otherwise. Also Isis is funded by Saudi and the Gulf states and the US keeps silent about it on purpose for whatever reason they have.

As a point of information the West would love to see a modern liberal democratic middle east with the rule of law and guarantees of individual freedoms.

We have spent the longest war in Britian's history attempting to create just that in Iraq and Afganistan. We have failed. To our none-understanding the locals don't want it.
