I'm not going to debate a vague point. Bush messed up, in my eyes, with the Iranians and putting them in the Axis of Evil while they were secretly working with us. Lead to IEDs being manufactured in Iran and a proxy war in Iraq. Could have arguably acted to support the idea that militant actions were more acceptable [in Gaza], but if you want to call that a stretch I'd concede without looking deeper into it.
AIPAC is less influential than the arms industry.
I just grabbed that report but the point is there is
at least ten times the money going into arms as there is money going toward lobbying [just to Israel]. Maybe there is more bang for your buck lobbying, pardon the pun.
Again, Bush screwed a real chance to change relations without force.
