Was the lost at sea of the great ship, the Titanic, caused by the Extraterrestrial Alliance arranging collision with an iceberg as a way to mock human pride in their achievement?

This is very true, as we have told you before, and was done for exactly those reasons. It was simply to be a slap in the face, to humble humans, and make them fear innovation and moving forward aggressively with new technologies not yet proven, and this indeed created quite a setback both emotionally as well as practically speaking in terms of politics, planning, and the setting of expectations. This was foreseen and the reason they took this action—it was simply too great a chance to pass up to see humans fall flat on their face yet again as they do this over, and over, and over with every meaningful human achievement of greater capability. They will look for ways to spoil the party, and create a downside if at all possible, and will often participate and undermine things all along the way. This is how the advances in technology come to exist with built-in hazards—using toxic materials and harmful energies for their operation so the inadvertent and unavoidable exposure to humans causes unforeseen health problems. These, and many other examples, show the care and degree of sophistication and emphasis given to causing harm across the board. So they will do everything they can to see that harmful substances are used for cooking and for preparation of processed foods, and in every part of the agricultural operation from fertilizer, materials for feeding and treating livestock for pest control, for preservation of the food, and from all of the mechanical steps in harvesting, extracting, cleaning, preparing, and the blending of ingredients with all of the added materials—to assist in the processing and obtaining suitable shelf life under practical storage conditions requiring, as it does, chemical additives as well as things done to change physical properties that are desirable, and colorants, and various additional materials to alter and enhance flavor that may inherently be toxic. It takes relatively little effort to see to this while using mind control manipulation to dull curiosity, prevent detailed scrutiny of the undertaking, and make everyone involved complacent so they do not worry about long-term consequences, and will continue compounding basic problems over and over even as signs of trouble appear. This shows the level of depravity of those who truly run things from behind the scenes.
