Why does the following always get explained as only, "the generation that sees Israel become nation"?

Rather than, "the generation that shall see all these things"?

Matthew 24:33 So likewise ye, when ye shall see all these things, know that it is near, even at the doors.

  34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.

It doesn't speak about only seeing "one" thing, i.e. only speaking about Israel becoming a nation.

But doesn't it speak of seeing all these things, which would "include" Israel becoming a nation, again?
