Most pro-Israel US congressmen like to work in quite behind the scenes and getting that last UN veto forced them to work in the open, which is dangerous for them politically. Money has the most influence from the shadows and is limited in buying public opinion out in the open. Jewish voters are only 1.6% of US population, so keeping most US voters focused on other issues is critical for pro-Israeli congressmen to remain in power.
