There obvious current goal worldwide is the same one muslims had in the 7th to 15th Century - the utter destruction of Western Civilization and the destruction of Christianity. They did it once, and the way everyone shrinks from speaking the truth of Islam, we are in the road to a repeat along with the attendant Dark Ages.
And no, muslims did not invent or build anything, they just preserved bits and pieces of Western, Persian, and Hindu cultures/knowledge that suited some individual's fancy, while slaves [ mostly Jews ] build and decorated various buildings.
The only known invention by a muslim is the cell phone bomb invented by some anonymous Palestinian. Everything else attributed to them they stole from others.
Even the Dome of the Rock and the Al-Aqsa Mosque are frauds. Before the temple was built, Jerusalem was a backwater town populated by goat herders. Far away in Amman, Jordan, the capital of the current Caliph, the Court was restless, so fearing some trouble from them the Caliph moved the court to Jerusalem, where he used his Jewish slaves to build them. Included with the building, he let the Court know that this was the spot were Mighty Mo ascended to Paradise. Every one knew that was a lie, as there was no way Mo could have gone so far with the assassins after him. [ He likely was killed in some far mosque in Medina. ]
The Court was pleased with this take, as they could then tell the unwashed to come to Jerusalem as pilgrims for a "small" fee. Years past and the Court once again grew restless, so the Caliph, without ado, moved the Capital back to Amman. A certain muslim family to this day still collects fees from the fraud.
