The Iranian Revolution was victorious in 1979. Nearly 40 years ago. On February 11th, 1979, Khomeini declared victory and flew into Tehran that day. This day was the eve of Tu B'Shevat of 1979.
There have been seven presidents from 1979 to our current year of 2019. The current incumbent, Hassan Rouhani, was born on November 12th, 1948. Approx. 6 months after Israel's rebirth. He assumed office on August 3rd, 2013. He has been in office nearly 6 years.
Iran / Persia is Israel's greatest and most dangerous enemy to modern day Israel. Iran and it's proxies have sworn to totally wipe Israel and her people off the map. The wise old adage to "know thy enemy" is very apt. Hence the research I am doing. The first link is from Wikipedia re Iran's 7 presidents from 1979 (the revolution) to 2019. Scroll down to see the photos and brief outline. The 2nd link is written from an Arab perspective and is called The Seven Presidents. The 2nd link gives greater detail of each president and shows the tie that binds - hatred of Israel and the USA.
Are these the 7 kings? With an 8th due? I have no idea but I find it intriguing that we have 7 presidents of Iran / Persia and this is the country that poses the most danger to Israel. THIS makes them important in end time prophecy. Well worthy of researching.
