Here's a little riddle for you.

There had to be another piece of the jigsaw.

When the Fed ends a liquidity squeeze, it turns the pieces right side up. So it is easy to reassemble the puzzle.

I take all the little pieces and I put the pieces together like a puzzle.

If you do this, you get the last puzzle piece, which is water.

But it isn't just about growing, because we all are part of this jigsaw.

And the next piece of the jigsaw is about four women across three generations shaping a new life together.

The next piece of the jigsaw is of a boat in the early dawn slipping silently out to sea.

It consists of three rods, and a number of disks of different sizes which can slide onto any rod.

In order to do that in 20 minutes, I have to bring out four ideas it's like four pieces of a puzzle.

The war in Lebanon, so frustrating for Israel, accelerated that subtle change. Now Europe and its various contingents are playing a leading role in picking up the pieces there.

So the final part of the puzzle is, how do you make all this work financially, especially when the people can't pay for it?

Indeed, I believe that things are even worse as long as aggregate demand remains low, we cannot even tell which pieces are right side up.

Because Europe remains entangled in this seemingly insoluble conundrum, Israelis see it as trying to compensate for its lack of political effectiveness in Middle East diplomacy with unbearably self righteous and moralistic talk.

This does not sound like a partial or proselytizing body, but one that has striven to assemble, order, and make sense of a rapidly evolving scientific puzzle for which new pieces emerge almost daily while others remain to be found.

So, those who are grappling with the Afghan riddle today should consider, first and foremost, the regional realities can the West afford to withdraw? If so, we should pull out of Afghanistan immediately.
