Take a look at the picture below - at the smiles on the faces, at the flag waving in the air. This is how Palestinians in Gaza reacted last night to the news that a terrorist had murdered 8 young Israelis at the Mercaz HaRav Yeshiva in Jerusalem.

Take a good, long look, and accept the cold, hard truth: there is no negotiating with evil. There is no compromise with those who cheer the death of innocent teenagers.

This isn't about a political dispute or an ideological difference. As far as our enemies are concerned, this is a war of extermination, and they are just going to keep on coming over the hill until only one side is left standing.

This is the evil that we face.
