Why does Israel provoke terrorists?

Masked Palestinian militants of the Popular Front for the Liberation of Palestine carry assault rifles as they stand in front of burning tires, during a protest condemning the capture of their leader Ahmed Saadat and five other Palestinians during an Israeli raid Tuesday on the prison in the West Bank town of Jericho, in the Ein-el-Hilweh Palestinian refugee camp, near the southern port city of Sidon, Lebanon, Wednesday, March 15, 2006. Israeli officials said Wednesday that they are determined to put Palestinian prisoners seized from a West Bank jail on trial for the killing of an Israeli Cabinet minister, but will first have to overcome some legal hurdles.

Israel seem to continuously provoke these reactions from Palestinian - don't they understand that their aggressive policies will thwart any chances for peace with Palestine, especially with Hamas in power there now
