Thank you for your questions:
It is the way of the Prophets and the elect of human beings since our father Adam through our father Abraham then Moses, Jesus, and Muhammad, upon them blessings and peace, consisting in true worship of our Creator and excellent living and dying until we return to Him and enter everlasting life, in which this life forms less than a drop in the ocean; a way the formal description of which is  belief in the one God alone without partner, son, or spouse, in the angels, the Divine Books, the Prophets and Messengers, the Day of the Resurrection and Judgment, and the foreordained Divine decree that includes both good and evil, and  praying the five prayers in their appointed times every 24 hours, remitting the poor-due, fasting the month of Ramadan, and performing, if physically and monetarily able, the pilgrimage to Makka.
All three dispensations are indeed from the same Divine origin and we believe that Religion is one just as God is One, the same One that sent all the Prophets and Whose basic message does not change.
Islam is the unadulterated form of their message but addressed to all creation, a universal Last Testament.
No more for the Zionists than for those whom they have been plundering, oppressing, and killing mercilessly since that conflict began.
There is no hatred towards "the Jews and Christians" but hatred towards injustice and oppression, hence expressions as those attributed to Jesus in the Gospel such as "whitened sepulchres" and "race of vipers" to characterize attitudes that ultimately stem from satanic pride and which are also excoriated in other Divine admonitions including the Psalms and the Qur'an.
The reason why the latter describes the Christians as generally closer to the truth is only insofar as they tend to be more devoid of that trait; further, they reject only one of the Prophets of God (Muhammad) while the others reject two (Jesus and Muhammad).
It is advancing by the grace of God despite any appearance to the contrary. The ending has already been written and it is to the honor and glory of God and His Prophets, let the enemies try what they may.
The Sudan has been the object of a systematic campaign of defamation in the Western press and the second question apparently presupposes the misconceptions born of such a campaign, however, I leave both questions to others more qualified to answer them.
As far as any true and sincere people of faith and goodness can see, true Muhammadan Islam is the last remaining living Divine recipe for enlightened belief and right living in the highest desirable sense for all human beings. It makes perfect sense that the enemies of the human race should therefore focus on the poisoning, corruption, and demonization of Islam whether through aggressive, insane chaos or through a reptilian discourse that poses as reasonable and historical but strives even more desperately and aggressively to represent the followers of the most perfect man ever to walk the earth as fanatic loons. See, for example, the hate site "jihad watch."
However, the last word belongs to the owner of this Religion which is God Himself--a fact of which there is no escape. Hence the vanity of the misrepresentation that is going on, of which the situations mentioned are mere elements, and their ultimate irrelevance to the endurance of Islam as the last Godgiven way of safety and salvation.
