Could the current events in the world mean the End-Times are approaching?

Your points are in line with truth but before 1948 those that predicted the end times were wrong because all of the prophecies had not been fulfilled. Salvation came first to the Jew then the Gentile. Do most Jews accept the Salvation of JC? No. Does God leave anything undone? No. When Israel became a nation again in May 1948 that signaled that we were in the end times and the fullness of the gentiles was almost complete because against all odds Israel became a nation again and God will finish what He started. It is only those who have their faith in man solving his own problems that can't see through the drama of this world to see who has been in control all this time.
