There will eventually be a worthless treaty that will be confirmed by the Antichrist and begin the Tribulation Period.
Don't be too sure of these assumptions. Odds are they're wrong. "It's not what you don't know that hurts you, it's what you think you know, but don't" - Mark Twain
For example, the 7 years could be 7 periods of 7 years, a Jubilee. Israel signed the first treating in September 1978. The 50th year will be 2028, which just happens to be exactly 2,000 years since Christ was Crucified!
A great many things happen in this pattern of sevens. We're (today's bible scholars) quite ignorant of how and when the "End Times" are going to play out. IMO, we're into them or on the cusp of the start of a new age now. That said, I'm not 100 percent certain, but about 90% certain.
What's the danger? The danger is the end times may be much closer than anyone thinks. Christ said he would come for His when we least expected it. His warning is for those who need to clean up their act.
Maybe we can all agree, at least, this seems to be the season.
Excellent contribution to this thread.
