That is not "winning".
The "will" that was broken in Germany in 1918 was totally revitalized by 1939. Hamas' "will" has a much shorter recycling time.
Why have we not had any trouble in Germany since 1945?
Because the Nazi leadership did not have their "will" broken. They had their bodies killed.
Right now, Israel has Hamas in a situation the U.S. could only dream of having Osama bin Ladin and al Qaeda in: Completely surrounded by their armed forces.
If Israel wants to win, Israel needs to do more than break the will of Hamas. Israel needs to kill Hamas.
Nailed it.
