Thank you for a well-written and highlighted post
Here's a couple of thoughts: The FDS says "We need not look for news reports that governments are slowly becoming more supportive of the United Nations". So then, we need not look for news reports because there won't be any clues or hints beforehand. As Br. Jackson said "It will be an act of God". Although there won't be any discernible 'signs', we have already been alerted that it will happen, and that's what we needed to know.
In contrast, 1 Thess 5:3 says "Whenever it is that they are saying, "Peace and security!" , then sudden destruction is to be instantly upon them, just like birth pains of a pregnant woman." So, this prophesy tells us the nations will be "saying" their belief that P&S is at hand, or even accomplished. This demon-inspired propaganda will fill the earth, misleading most. So, this prophesy does unfold slowly, and we do well to pay attention to events that align with it. Remember, the verse says "just like birth pains of a pregnant woman". Expected, anticipated. Increasing in frequency, intensity and duration. Once labor pains begin, a woman knows that an unstoppable process has begun.
How Jehovah puts it into their hearts to "carry out his thought, yes, to carry out their one thought by giving their kingdom to the wild beast" we don't know. But I can't see any reason why it wouldn't be in collaboration with the United Nations itself. I look forward to what comes out of the next General Assembly.
