The strongest weapons Israel has are not nukes, helicopter gunships or amoured tanks - their strongest weapon is to call anyone who disagrees with them anti-Semites. And everyone is too terrified to be branded thus, that they give in to whatever Israel demands! So that even though the tanks and gunships do a hell of a lot of damage to, eg. Lebanon, Gaza, Sudan et al, the fear of being called anti-Semite stops the US from doing what should be done about Israel, ie to cut their funding so they can't continue bombing the s..t out of everyone they don't like.
