When it comes to terrorism, it's very much about Bush v. Kerry. If Kerry wins, I have no faith that we'll do much to protect ourselves. Israel was right to force the plane to land elsewhere. If others insist on being Kerry-like about inspections, then let their countrymen/airline customers suffer for it. No need for the plane to blow up in Israel.
I think Kerry will try to copy Clinton. "Talk and wait. Then eventually do something." But because your country is stressed a lot because of Iraq and Afghanistan, I don´t think that Bush has many alternatives left for Iran or N Korea.
