I've heard it suggested that they didn't expect to get as far as they did into Israel and they barely expected to get past the border wall. If that's the case they may not have planned what to do when they did and so there may be no grand strategy behind some or all of it.

I'm not sure why, in the 21st century, we have clocks that can tell the wrong time.
