In my opinion, it’s even simpler than that.
Hamas and other jihadis are lobbing qassams daily into Israel.
Most of the attempted suiciders and other types have been caught
at the border.
They found 5 tunnels around the 24th of the month I believe it was.
The jihadis use it for weapons/other goods smuggling.
Several attempts have been made by the jihadis to place explosives at
the security fence line.
Maybe Israel has had enough and is fighting back.
As for half-heartedness, I agree. Olmert needs to be agressive.
It is clear that the average Israeli has had enough. Too bad they are stuck with the cowardly lion for a president.
