I have been defending Israel's right to exist, and to defend itself against terrorism, for many years-on college campuses, in television appearances and in debate.
It simply cannot be disputed that for decades the Palestinian leadership was more interested in there not being a Jewish state than in there being a Palestinian state.
The defendant wants to hide the truth because he's generally guilty. The defense attorney's job is to make sure the jury does not arrive at that truth.
The prosecution wants to make sure the process by which the evidence was obtained is not truthfully presented, because, as often as not, that process will raise questions.
