Dear Nicole & Fellow Watchers:
I realize that the various timelines proffered are many times fractals of sorts; where similar patterns can repeat themselves with slight or greater variances. If all are considered and none excluded then we begin to realize the magnificence of nature and nature's God. So, let's not exclude the possibility that the 7 year tribulation has not yet commenced.
You said, "The Blood Moons of 2014/2015 represent a sign in the Heavens of the Great Tribulation...and whether that means it is the middle or the end of the tribulation, I do not know. "
If you click the 2nd reference above you will see that Israel was declared sovereign BEFORE the 1949/1950 Tetrad.
