We do not play with kid gloves. We kill the people who launch the missiles with fire.
We do not. I repeat not. Slaughter innocent people, and we should not deny innocent people the basic right to trade peacefully with others.
The Palestinian terrorists do not pose a threat to the existence of Israel. They at best pose a threat to some individual citizens, and the Army, Navy, and Air Force are doing a very good job in defeating this threat. There's no need nor any purpose accomplished in harsh measures against peaceful Gaza citizens when the Army, Navy, and Air Force are already doing a good job smashing up the people who are not peaceful.
Had there been a serious threat from Gaza of destroying Israel, or even doing something more than launching glorified bottle rockets that hit Israel. During Cast Lead alone, the IDF killed (according to Hamas' own public forums) at least 433 members of Hamas and its associated groups.
This means that for every Israeli soldier and civilian killed by Hamas during Cast Lead, the IDF killed 48 members of Hamas and its affiliate groups. (I am omitting Palestinian civilian casualties from this count.) 120 more men were taken prisoners, or 13 prisoners for every Israeli killed.
No nation that exacts a price of 48 enemy combatants for each of its casualties can be seriously referred to as 'playing with kid gloves'.
