"Like a viper"

Bookworm writes,

For a while there, despite people’s concerns that Obama would use his lame duck period to shaft Israel, things looked relatively peaceful. We should have known that Obama, like the viper he is, would hide until ready to strike, and strike he did. And like a viper, he didn’t even stand up in a manly way and turn on Israel. Instead, he “abstained,” allowing Israel’s enemies a clear shot at her.
